Trial reportVaccine2019
A descriptive analysis of transgender participants in phase 1-2a trials of the HIV Vaccine Trials Network (HVTN) in the United States and Peru.
Trial report in Vaccine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundHIV disproportionately impacts transgender populations globally, creating challenges to inclusion in trials requiring low HIV risk profiles (LHRP) for acquisition. Our knowledge of transgender individuals with LHRP is limited. We conducted an analysis of transgender and cisgender individuals in HVTN trials enrolling individuals with LHRP.
methodsWe analyzed data from 694 participants enrolled in the phase 1-2a HVTN trials in the US and Peru from 2009 to 2014 that included individuals who reported gender identity (GI) differing from assigned birth sex (transgender [TG]), and compared them with those who reported a congruent GI (cisgender [CG]).
results681 participants (98%) were CG and 13 (2%) were TG. Mean age was 25 years. 16% were Hispanic and most (69%) were White. Reasons for enrolling included to help find an effective vaccine (TG 100%; CG 98%) and help their community (TG 100%; CG 96%). Significant differences by GI were observed in reported pre-existing conditions (p = 0.004); however, approximately 10% of pre-existing conditions reported by TG were GI-related (e.g., gender dysphoria). Significant differences were observed in hormone therapy use (p < 0.001) and mental health medications (p = 0.007). Retention was excellent with 2.1% missed visits and no discontinuations of vaccination for TG and 3% missed visits and 7.1% discontinuations among CG. There was no statistically significant difference in HIV incidence.
conclusionsPrimary reasons for participation were altruistic for all participants. Comparable to CG counterparts, TG participants maintained LHRP, followed trial procedures, and had high retention, facilitating meaningful early phase HIV preventive vaccine trial contributions.
