(Please upload your review as an attachment if it exceeds 20,000 characters)--> Reviewer #1: The manuscript is written in a scholarly manner with standard English used. However, there are some areas in the different sections of the manuscript that need clarity, as indicated in the attached comments, to make it read better. I have suggested some revisions to the Methods, the Results and Discussion. Reviewer #2: This is a well-conducted and timely qualitative study that addresses an important gap in the acceptability of multiplex self-tests for HIV, HBV, and HCV among key populations in two high-burden settings. The multi-method approach, direct engagement of PWID, HCPs, and stakeholders, and practical feedback to manufacturers on IFUs are notable strengths. The manuscript is clearly written and provides valuable insights for implementation. Please a summary of the strengths and few areas of improvement. Strengths • This is a Multi-country and Multi-method Design and Conducting the study in two diverse settings (Indonesia and Kyrgyzstan) provides comparative insights into cultural, healthcare, and policy differences, enhancing the applicability of findings to low- and middle-income countries (LMICs). The use of FGDs, SSIs, and cognitive interviews adds depth and triangulation, increasing data richness and reliability. • The Inclusion of Key Populations and Stakeholders and Engaging PWID (a hard-to-reach group), HCP, and policymakers ensures voices from end-users and implementers are represented, making the results practical and relevant for real-world deployment. This is encouraging to see such a study prioritizing these marginalized groups • Great and Practical Recommendations for Manufacturers: Cognitive interviews led to actionable IFU improvements (e.g., larger fonts, simplified language, clearer control line explanations), which were shared directly with manufacturers, demonstrating direct impact on product design. (Improvements suggested below ) • The Focus on Underserved Issues and Addressing a literature gap on multiplex ST acceptability for HIV/hepatitis, with emphasis on barriers like stigma and counseling needs is commendable, this aligns with WHO self-care guidelines and contributing to universal health coverage goals. • The analysis on Comprehensive Facilitators and Barriers is good and Identifies nuanced preferences (e.g., blood vs. saliva samples by country) and service delivery models (e.g., NGO-based in Kyrgyzstan vs. pharmacies/online in Indonesia), providing a holistic view for policy and program design. Recommendations for Improvement • Enhance Clarity and Consistency of Sociodemographic Reporting Table 2 contains formatting errors and incomplete data (e.g., age means and ranges are misaligned across columns, percentages sometimes do not add up correctly). Clean and double-check the table for accuracy before final publication to avoid reader confusion. • Provide More Detailed Description of Cognitive Interview Findings The abstract and discussion mention that cognitive interviews led to recommendations (larger fonts, simplified language, better explanation of control lines), but the manuscript (in the provided pages) does not yet include a dedicated results subsection or table summarising the specific problems identified for each of the four manufacturers’ IFUs. Adding a concise table or bullet-point list of the most common comprehension issues and the exact changes suggested per brand would greatly strengthen the paper and make the practical contribution more visible. • Include the Revised IFUs or Visual Examples Since the study’s major tangible output was improved IFU that were returned to manufacturers, consider including (in supplementary material) before-and-after examples of the most problematic sections (e.g., result interpretation diagrams or text passages). This would allow readers to see the concrete impact of participant feedback. • Strengthen Potential Bias Discussion The researchers in Kyrgyzstan were affiliated with the harm-reduction NGO partner (Attika), and in Indonesia worked closely with local drug-user networks. While this peer-led approach is a strength for access and trust, explicitly discuss how this proximity was managed to minimise social-desirability bias in responses (e.g., participants possibly overstating acceptability to please familiar organisations). • Improve Transparency on Saturation The sample size for cognitive interviews was planned at 10–15 per IFU “or until saturation”. State clearly whether saturation was reached for each of the four IFU and, if not, note which aspects remained uncertain. • Minor Methodological Clarifications o Specify exactly how the IFU scores (0–10) given by participants were analysed and whether average scores per manufacturer are available. o Briefly explain why no actual self-test kits were used (only printed IFUs) and acknowledge this as a limitation for assessing real-world usability (e.g., finger-prick difficulty, blood volume, timing).Or just state this clearly as a limitation and may be a recommendation for future studies. With these minor revisions, the manuscript will be suitable for publication in PLOS ONE. Thank you for the opportunity to review this work. ********** -->6.

(Please upload your review as an attachment if it exceeds 20,000 characters)--> Reviewer #1: The manuscript flows smoothly and I wish to thank the authors for incorporating the comments. However, the authors need to thoroughly read through the manuscript and fix a few typo and grammatical errors and punctuation (e.g. pg 6, the first sentence in the last paragraph or pg 7 & 8, where you need to match the numbers with the noun’s plurality – 1 man, 2 women). Other than that, I do not have any more comments. Reviewer #2: This manuscript presents a robust qualitative study on the acceptability of multiplex self-tests for HIV, HBV, and HCV among PWID, HCPs, and stakeholders in Indonesia and Kyrgyzstan. The multi-method approach, including FGDs, SSIs, and cognitive interviews, effectively captures perceptions and optimizes IFU, addressing a critical gap in self-testing implementation. Strengths include diverse participant engagement, practical manufacturer feedback, and alignment with WHO guidelines. Overall, the work offers valuable insights for public health strategies and merits publication in PLOS ONE ********** -->7.
