                    <title>Background</title>
                    <p>Sushruta (600 B.C.) described a condition called &#x201c;Vidari&#x201d; linked with progressive narrowing of mouth, depigmentation of the oral mucosa, and pain on taking food, oral submucous fibrosis (OSMF). With an overall Indian prevalence rate of between 0.2&#x2013;0.5%, OSMF is primarily found in India and Southeast Asia, according to global estimations. Patients with OSMF need regular follow-ups and to maintain this follow-up it is not always possible for the patient to visit a dental clinic. Hence developing a smartphone-based application for the follow-up of OSMF will be of great value to the patients. The study aims to evaluate the effectiveness of a smartphone application on OSMF self-examination in the follow-up of patients.</p>

                    <title>Methods</title>
                    <p>There will be three phases of the research. The first phase will be the development of a smartphone-based application for the follow-up of patients with OSMF. The second phase will be distribution and training the patients regarding the usage of the application and the third phase will be evaluating the effectiveness of the smartphone application in maintaining the follow-up of the patients.</p>

                    <title>Expected results</title>
                    <p>The follow-up of patients with OSMF is expected to be better and feasible using a smartphone application as compared to regular Outpatient Department-based follow-up.</p>

                <sec>
                    <title>Conclusions</title>
                    <p>Designing a mobile application for the ease of users presents difficulties since it must take user-friendliness and accessibility into account, which influences how well the application is received by users. In addition to follow-up, the smartphone-based application promotes the awareness towards Self-examination and knowledge in OSMF patients. Thus, it will act as an educational tool providing information, to enhance OSMF screening practice.</p>

                <title>Amendments from Version 1</title>
                <p>The revised version of the article has explained the phases of the study along with the timeline and medical intervention, while follow-ups are added to the methodology of the article. In addition, the article has clarified the patient outcome, generalizability, and effectiveness of smartphone applications in augmenting patient compliance, follow-up, and awareness towards self-examination in OSMF screening. Thus, a defined timeline of all the phases has been added to the manuscript. The modifications in the smartphone application will be done according to feedback on the patient's understandability and usability regarding the self-assessment of any parameter of OSMF. To assess the effectiveness of the intervention being tested, the authenticity and reliability of the self-assessment findings will be cross-checked in 15 participants of the intervention group. These 15 patients will be called in OPD, and the submitted data of these patients through a smartphone app and observations on physical examination will be compared. A new author was added to the paper for their contributions.</p>

                <p>The World Health Organization (WHO) described this condition as &#x201c;a slowly progressing disease in which fibrous bands form in the oral mucosa, ultimately leading to the severe restriction of movement of the mouth including tongue&#x201d; in 1978.

                <title>Prevalence</title>
                <p>According to estimates, 7&#x2013;30% of oral submucous fibrosis (OSMF) cases will develop into oral squamous cell carcinoma (OSCC).
                    <sup>
                        <xref ref-type="bibr" rid="ref4">4</xref>
                    </sup> Due to the high malignant transformation rate of this illness (1.5&#x2013;15%), death rates are high. OSMF incidence varies by area and ethnicity and is strongly correlated with culture, habits, and diet.
                    <sup>
                        <xref ref-type="bibr" rid="ref5">5</xref>
                    </sup> Patients with OSMF are most predominant in South and South-East Asia. The high percentage of Indian immigrants in South Africa also contributes to the high prevalence of patients with OSMF there.
                    <sup>
                        <xref ref-type="bibr" rid="ref6">6</xref>
                    </sup> Different South-East Asian nations have different oral submucous fibrosis (OSMF) prevalence rates. According to statistics, the prevalence is 0.9&#x2013;4.7% in China, 0.6&#x2013;6.42% in India, 0.15&#x2013;14.6% in Vietnam, and 0.086&#x2013;17.6% in Taiwan. According to statistics from WHO, more than five million individuals are living with OSMF worldwide.

                    </sup> Patients with OMSF can range from 8 to 80 years old, and the mean age varies between studies.</p>
                <p>OSMF is closely linked with the use of betel nut/areca nut, which is classified as grade I hazard by WHO. The use of betelnut is very common in the Indian population being part of cultural events. The betelnut and its products are easily accessible.

                    <italic toggle="yes">e.g.</italic>, kharra, gutkha, and processed packed supari, are very common in this region, giving rise to the number of patients with OSMF.</p>
                <p>The oral mucosa of patients with the condition has a leathery feel and perceptible vertical fibrous bands, which finally restricts mouth opening and makes the tongue hard. Early signs of the condition include a burning feeling when eating spicy food, losing normal pigmentation, and blanching of the mucosa. Ulcers, dry mouth, burning in the mouth, and restricted mouth opening are some of the clinical symptoms of OSMF.

                        <xref ref-type="bibr" rid="ref9">9</xref>
                    </sup> As the condition worsens, it could cause distress to the throat and esophagus, causing fibrosis of the upper digestive tract, while mouth-opening limitation is triggered by fibrosis of oral mucosa in the late phases of OSMF. Oral mucosa blanching is a significant clinical characteristic in the initial phases.
                    <sup>
                        <xref ref-type="bibr" rid="ref7">7</xref>
                    </sup> Life quality is directly impacted by the characteristic manifestations and signs of OSMF patients who exhibit a constrained mouth opening.

                        <xref ref-type="bibr" rid="ref5">5</xref>
                    </sup> It should be noted that many patients with OSMF exhibit symptoms of anxiety, sadness, stress, and poor social interaction, and the incidence of these symptoms is proportionally linked to the severity of ailment&#x2019;s.

                <title>Intervention</title>
                <p>The participants of the intervention group will be given access to smartphone application for the follow-up of the OSMF. Whereas the control group will not be given access to the application. The participants in the control group will be referred to the OPD for the follow-up of OSMF.</p>
                <p>The intervention will be accustomed for six months. The initial two months will be the training period for the participants for the usage and various features of the smartphone application. The smartphone application will also be surveyed for any modifications in the smartphone application.</p>
                <p>The smartphone application will contain monthly and weekly follow-ups for the users and information regarding the disease and ill-effects of the use of betelnut and its products. After downloading the application, the user will have to fill the demographic details for the sign-in of the application. After the sign-in, the user will have access to follow-up section and the information available on the smartphone application. The user can follow the steps and answer the questions of the follow-up for the monthly and weekly follow-up.</p>
                <p>To improve the adherence of the participants in the intervention group, the smartphone application will have a feature of notification reminder to adhere to the follow-up of OSMF on weekly and monthly basis.</p>
                <p>All the participants of the control and intervention group will be provided with the medicinal treatment over a period of 6 months. As all the participants are recruited from the OPD-setup, the participants will be examined and will be provided with medicinal treatment depending on their grades or severity of OSMF. Also, all the participants of the intervention group will be in contact with the investigator through telephonic communication. As the main objective of the smartphone application is maintaining long-term follow-ups and patients compliance, more emphasis is given on regular follow-ups.</p>

                <title>Outcomes</title>
                <p>The outcomes of the study will be measured in terms of augmented patient compliance and regular follow-up of the patients who have OSMF or have the habit of betel-nut chewing. In addition, the smartphone application will be of help in increasing awareness and promoting self assessment in OSMF patients. The participants can adhere to the follow-up more efficiently using the smartphone application for the follow-up and inspect for the improvement of the signs of OSMF on their own. It may not be always feasible for the patients to travel and report the OPD-setup for every-follow-up. Many patients residein the remote regions which are very far from the OPD-setups. Moreover, the patients must maintain long term follow-ups for OSMF, as it has high rate of malignant transformation. Development of such smartphone applications would be very beneficial in maintaining patient compliance and long-term follow-ups of patients.</p>

            <p>The follow-up of the OSMF patients is expected to be better using a smartphone application as compared to the regular OPD-based follow-up. Numerous studies on these applications have been carried out, and more than 40,000 mobile health applications are already accessible on several platforms. However, there isn&#x2019;t enough research to prove that these mobile apps integrate theory and were created using a qualitative design process. However, as mobile health technologies advance, there is growing concerned about how mobile application performance is constrained by their usability, accuracy, and data privacy.

                <p>The adverse habits such as consumption of betelnut chewing and tobacco chewing are prevalent in Indian population, consequently prevention and development of oral potentially malignant disorders such as OSMF is of concern. The population that consumes betel nut and tobacco products is the main focus of the study. The consumption of betel nut and tobacco products is done by a vast number of the Indian population. It is not always feasible for the patients to visit a dental setup for maintaining the follow-up.

            <p>The concept of the study is very sound that the patients will be monitored using the smartphone. It can improve patient compliance, enable remote monitoring, and support early intervention, ultimately reducing the disease burden and preventing malignant transformation.</p>
            <p> While India has seen rapid growth in mobile technology, recent surveys suggest: 
                <list list-type="bullet">
                    <list-item>
                        <p>The use of Smartphone still uneven in our population &#x2014;higher in urban areas, lower in rural.</p>
                    </list-item>
                    <list-item>
                        <p>Elderly patients may have very limited digital literacy and those from lower socioeconomic strata may not own smartphones&#x00a0;</p>
                    </list-item>
                </list> The other important point is that the monitoring features includes only timely follow-up and educational features. There should have been a wider range of symptoms that can be monitored using the app.</p>
            <p>Is the study design appropriate for the research question?</p>
            <p>Partly</p>
            <p>Is the rationale for, and objectives of, the study clearly described?</p>
            <p>Yes</p>
            <p>Are sufficient details of the methods provided to allow replication by others?</p>
            <p>Partly</p>
            <p>Are the datasets clearly presented in a useable and accessible format?</p>

            <p>The protocol raises several important concerns. One important issue is the lack of clarity about whether medical management or clinical interventions will be part of the follow-up process. This information is critical to assessing the effectiveness of the smartphone application for patients with OSMF.&#x00a0;In addition, the protocol doesn't provide adequate information on how participants' privacy will be protected, particularly with regard to the protection of their personal health data. This is a critical issue in mobile health research.&#x00a0;The study also lacks a clear definition of how the application will affect patient outcomes, leaving questions about its practical relevance unanswered. The sample size calculation is overly complicated and difficult to verify.&#x00a0; The study also does not include a well-defined timeline or feasibility analysis for the phases of the study, in particular how the application will be modified based on user feedback.&#x00a0;Without clear results, it is impossible to assess the effectiveness of the intervention being tested.&#x00a0;</p>
            <p> I recommend not indexing of the study protocol due&#x00a0;to significant gaps in methodology, ethical considerations and feasibility.</p>

                <p>The protocol raises several important concerns. One important issue is the lack of clarity about whether medical management or clinical interventions will be part of the follow-up process.</p>
                <p> - Yes, all the participants of Control (OPD-based follow-up) and intervention group (smartphone application-based follow-up) will be provided with medicinal treatment or clinical intervention. For both groups, patients will be recruited from outpatient department, the treatment protocol will be explained and medications will be prescribed at first visit.</p>
                <p> &#x00a0;&#x00a0;&#x00a0;&#x00a0;&#x00a0;&#x00a0;&#x00a0;&#x00a0;&#x00a0; In control group, as the patients report to the OPD for every follow-up, the participants are examined and medicinal treatment is provided to them depending on their grades or severity of OSMF. For intervention group, the follow-up information of the participants is recorded via smartphone application as well as participants will be in contact with the researcher through telephonic network. The medicinal intervention to the participants of intervention group will be done through telephonic communication.</p>
                <p> </p>
                <p> This information is critical to assessing the effectiveness of the smartphone application for patients with OSMF.&#x00a0;In addition, the protocol doesn't provide adequate information on how participants' privacy will be protected, particularly with regard to the protection of their personal health data. This is a critical issue in mobile health research.&#x00a0;</p>
                <p> - All the data of the participants in intervention group will reach the investigator through an account created in the same smartphone application for which only the investigator has access. No other person is able to login into the account in smartphone app of patient related data other than the investigator.</p>
                <p> </p>
                <p> The study also lacks a clear definition of how the application will affect patient outcomes, leaving questions about its practical relevance unanswered.</p>
                <p> -As OSMF is a chronic disease which needs regular and long-term follow-up and patient compliance due to its high malignant transformation rate, development of such smartphone application can be beneficial in maintaining the follow-up in the patients who are unable to report to OPD for follow-up.</p>
                <p> </p>
                <p> </p>
                <p> The sample size calculation is overly complicated and difficult to verify.&#x00a0;</p>
                <p> The sample size &#x00a0;formula has been edited and simplified in consultation with statistician.</p>
                <p> </p>
                <p> The study also does not include a well-defined timeline or feasibility analysis for the phases of the study, in particular how the application will be modified based on user feedback.&#x00a0;Without clear results, it is impossible to assess the effectiveness of the intervention being tested.</p>
                <p> - Defined timeline of all the phases have been added to manuscript. The modifications in the smartphone application will be done according feedback on the patients understandability and usability regarding the self-assessment of any parameter of OSMF. To assess the effectiveness of the intervention being tested, the authenticity and reliability of the self-assessment finding will be cross-checked in 15 participants of the intervention group. These 15 patients will be called in OPD and the submitted data of these patients through smartphone app and observations on physical examination will be compared.</p>
