Empowering at-risk Thai adolescents and young adults: an observational study of "Stand By You" - a person-centred online service model for HIV self-screening, text-based counselling and linkage to care.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionAdolescents and young adults (AYA) are disproportionately at risk of HIV acquisition. Person-centred online platforms could effectively reach AYA with HIV testing services. We assessed the effectiveness of Stand By You, a mobile application, in delivering HIV-related services to at-risk Thai AYAs.
methodsDeidentified data from clients who accessed Stand By You services between August 2022 and February 2024 were analysed. HIV self-testing (HIVST) services were promoted through TikTok influencers to target AYAs vulnerable to HIV. An automated chatbot provided real-time responses to client inquiries, and trained counsellors provided confidential, text-based counselling daily. Clients who completed risk assessments received personalized recommendations for HIVST based on their risk profile. Clients who submitted their HIVST results received post-test counselling and linkage to care and prophylactic treatment. Multivariable logistic regression was used to assess risk factors for reactive HIVST kit results. The per unit direct cost of the programme's performance metrics were assessed.
resultsA total of 8863 clients provided 11,536 risk assessments. The majority were male (76.3%), under the age of 30 (76.0%), identified as members of key populations (60.4%) and first-time testers (56.1%). Additionally, 27.8% had a history of sexually transmitted infections (3,202/11,536), 16.5% reported receiving money or incentives for sex (1908/11,536) and clients indicated an average of 2.6 sexual partners in the past month (SD 3.4). Out of 7585 submitted HIVST results, 3.6% were reactive (n = 274); 60.2% were linked to care (n = 165/274) and 10.4% are in the process of linkage (n = 23/274). Of the 5.3% invalid results reported (n = 401/7585), nearly all were non-reactive by the second HIVST (117/187). A history of testing HIV negative (adjusted odds ratio [aOR] 0.54 [95% CI 0.40-0.72], p < 0.001) and receiving pre-exposure prophylaxis (aOR 0.20 [95% CI 0.06-0.64], p = 0.007) were independently associated with reduced odds of a reactive result. Average direct cost was $18.7, $40.3 and $1100 USD per distributed HIVST kit, first-time tester and new client linked to care, respectively.
conclusionsAYA populations at risk for HIV can be effectively reached through mobile phone applications that provide services anonymously. Online strategies for HIVST delivery and supportive text-based counselling can generate high demand, engagement and successful linkage to care.
