Youth-Friendly Sexual Health Services and Peer Support for Improved Sexual and Reproductive Health Outcomes Among Adolescents and Young Adults in South Africa: Results of a Factorial Randomized Controlled Trial.
Trial report in Sexually transmitted diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAdolescents and young adults in South Africa have high burdens of sexually transmitted infections (STIs) and unintended pregnancy. We evaluated the impact of peer support and/or expanded sexual and reproductive health (SRH) services on STIs, contraception, and pregnancy in rural KwaZulu-Natal, South Africa.
methodsWe analyzed secondary outcomes from a 2 × 2 factorial randomized controlled trial conducted from March 2020 to August 2022 among 16- to 29-year-olds, comparing (1) enhanced standard of care (SoC), access to mobile youth-friendly HIV prevention (AYFS); (2) SRH, self-collected STI testing and referral to AYFS with expanded SRH services; (3) peer support, peer navigator facilitation of AYFS attendance; (4) SRH + peer support. At 12 months, all participants were offered STI testing; female participants self-reported contraceptive use and pregnancy.
resultsAmong 1743 trial participants (51% female), 927 (53%) had 12-month STI results; 209 (22.5%) tested positive: 163 (17.6%) chlamydia, 54 (5.8%) gonorrhea, and 44 (4.8%) trichomoniasis. The prevalence of STI was somewhat lower among those exposed to peer support (adjusted odds ratio [aOR] adjusted for sex, age, location, 0.77; 95% confidence interval, 0.56-1.06) or SRH (aOR, 0.74; 0.56-1.06) and, compared with SoC, was reduced in those exposed to both (aOR, 0.59; 0.38-0.94). In SRH arms, 64 of 469 (13.6%) had a new STI at 12 months, with no difference by peer support ( P = 0.97). Among females, 336 of 634 (53.0%) reported using contraception and 47 of 667 (7.1%) reported pregnancy, with little difference by study arm.
conclusionsPeer support and STI testing with expanded SRH each had no more than small effects on STIs, contraception, or pregnancy. Combined or more intensive interventions, for example, repeat screening, enhanced partner notification, and deeper understanding of structural drivers, are needed.
