SECONDARY, DISEASE, RECRUITMENT
This digital, crowdsourced, multilevel intervention is an effective approach to improve HIV testing uptake among MSM. Our findings highlight that such interventions should be made more widely available for HIV prevention and other public health issues.We appreciate all study participants for their participation. We would also like to thank staff members at Blued, the local community-based organizations, and Shandong Center for Disease Control and Prevention for their support.Authors' Contributions: WM, JDT, WT, CR, and Y Lin conceived the study. DK and ML participated in recruitment and gave technical or material support. ML, CR, KJ, ZX, ZZ, Y Lin, CL, LW, YY, Y Li, TW, and CC collected the data. Y Lin, WT, WM, CR, and KJ coordinated the statistical analysis. The manuscript was prepared by Y Lin, JDT, and WT and was carefully revised and edited by WM. All authors have reviewed and approved the final manuscript.Conflicts of Interest: None declared.CONSORT-EHEALTH checklist (V.1.6.1).Study setting. The control arm had 5 cities: Jinan, Weifang, Zibo, Jining, and Liaocheng. The intervention arm had 6 cities: Qingdao, Dezhou, Weihai, Binzhou, Heze, and Zaozhuang. Heze and Zaozhuang are in the same cluster.Randomization and masking.Digital, crowdsourced, multilevel intervention and schedule.Trial profile of each cluster.HIV seroconversion across 4 follow-up periods.Follow-up across 2 arms.Baseline characteristics of study participants stratified by loss to follow-up.Cumulative numbers of follow-up surveys completed.HIV testing frequency over 4 follow-up periods.Incident HIV testers in each follow-up period.HIV testing proportion by arm over 4 follow-up periods.Uptake of HIV self-testing kits.Effect of digital crowdsourced intervention on secondary outcomes.
