The primary outcome measured was the rate of retention in care posttransition. Data screening and extraction were performed using Covidence software, and the quality of included studies was assessed using the Joanna Briggs Institute tool.The one-year pooled retention rate was 81% (95% CI: 78%, 91%), while the two-year retention rate was 69% (95% CI: 53%, 83%). Significant heterogeneity was observed among studies (I² = 96.73%). Subgroup analyses revealed geographical differences, with Asia exhibiting the highest retention rates. Retrospective study designs yielded better retention outcomes.The findings underscore the challenges and variability in retention rates for adolescents transitioning to adult HIV care. There is a critical need for targeted interventions and improved follow-up strategies to enhance retention and meet global HIV care targets.
