1 · What the graph read from it

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.

2 · The registry

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

introductionTransgender women in Asia face a high HIV burden, yet remain underrepresented in pre-exposure prophylaxis (PrEP) research. Despite increases in PrEP availability, uptake among trans women remains low. This study examines PrEP awareness, use, and willingness among trans women across 11 Asian countries.

methodsData were drawn from the 2022 PrEP Product Awareness, Preferences, and Past Experiences Among Transgender Women and Men Who Have Sex with Men (PrEP APPEAL) study, a multi-country cross-sectional online survey. Two PrEP cascades were constructed: one assessing use (awareness, lifetime use, current use) and the other assessing willingness (risk, interest, and willingness to pay). Logistic regression models were used to identify factors associated with lifetime PrEP use and willingness to use PrEP.

resultsOf 1178 trans women participants, 80.0% (n = 942) had heard of PrEP. Among those who were PrEP-aware, 62.6% (n = 590/942) reported ever using it, and of these, 78.1% (n = 461/590) were current users. Among PrEP-naïve participants classified as at risk of HIV (n = 265), 60.0% (n = 159/265) were willing to initiate PrEP, yet only 34.0% (n = 54/159) were also willing to pay. Lifetime PrEP use was positively associated with wider country-level PrEP access (aOR = 4.34; 95% CI: 3.03-6.21), genital surgery (aOR = 1.54; 1.03-2.31), current romantic relationship (aOR = 1.65; 1.19-2.29), as well as reporting sex work (aOR = 1.51; 1.05-2.18), condomless sex (aOR = 1.76; 1.28-2.42), chemsex (aOR = 1.98; 1.36-2.87), and a recent sexually transmitted infection diagnosis (aOR = 2.28; 1.45-3.59) within the past 6 months. Negative associations included older age (aOR per year = 0.94; 0.92-0.96) and discrimination from healthcare workers (aOR = 0.66; 0.47-0.93). Willingness to use PrEP was lower among older participants (aOR per year = 0.97; 0.94-0.99) and those in countries with wider PrEP access (aOR = 0.53; 0.29-0.97), with no significant associations observed for behavioural risks.

conclusionsPrEP awareness was high among trans women in Asia. PrEP use and willingness were influenced by structural barriers (e.g. country-level PrEP access), healthcare discrimination, and personal factors (e.g. behavioural risks). Scaling up PrEP for trans women requires rights-based approaches and commitment to achieve equitable HIV prevention in the region.
