Prevalence of Reactive Rapid Test Results for Sexually Transmitted Infections and Associated Factors Among Transgender People Attending Specialized Health Services in Brazil.
Article in Infectious disease reports, 2026. 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
BACKGROUND/
objectivesTransgender (trans) individuals experience a disproportionate burden of HIV and other sexually transmitted infections (STIs), although evidence based on point-of-care testing remains limited in Brazil. This study aimed to estimate the prevalence of reactive STI rapid test results and associated factors among transgender individuals receiving care in specialized health services in São Paulo, Brazil.
methodsA cross-sectional study was conducted between July and December 2025 with 400 participants attending two specialized healthcare services. Sociodemographic, behavioral, substance use, clinical, and HIV prevention-related data were collected. The primary outcome was reactivity to at least one rapid test for HIV, syphilis, hepatitis B, or hepatitis C; reactive results could include previously known infections and therefore were not interpreted as newly diagnosed or active infections. Associations were estimated using Poisson regression with robust variance.
resultsOverall, 19.2% of participants had at least one reactive rapid test result, with HIV accounting for the largest proportion of reactive results (14.8%). In the adjusted model, increasing age was associated with a higher prevalence of the outcome (PR = 1.04; 95% CI: 1.02-1.05), whereas transgender men had a lower prevalence than transgender women (PR = 0.38; 95% CI: 0.19-0.73). Reported HIV prevention through PrEP and/or PEP was inversely associated with the outcome (PR = 0.37; 95% CI: 0.17-0.82); however, this association should not be interpreted as a direct protective effect because most reactive HIV results occurred among participants with previously known HIV, who would not be eligible for PrEP.
conclusionsThese findings indicate a substantial frequency of reactive STI rapid test results among transgender individuals attending specialized health services and support continued access to testing, prevention, and culturally competent sexual healthcare.
