Evidence of an untamed HIV epidemic among MSM and TGW in Rio de Janeiro, Brazil: a 2018 to 2020 cross-sectional study using recent infection testing.
Article in Journal of the International AIDS Society, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 papers, 1 of them a synthesis that pooled 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.
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
introductionMonitoring the HIV epidemic and identifying populations among whom HIV is spreading is critical. We aimed to provide an estimate of the annualized HIV incidence rate using recency testing among cisgender men who have sex with men (MSM) and transgender women (TGW) at a reference centre in Rio de Janeiro, Brazil.
methodsWe evaluated MSM and TGW who sought HIV testing at the Evandro Chagas National Institute of Infectious Diseases-FIOCRUZ between March 2018 and January 2020. The Limiting Avidity assay (LAg) as part of a recent infection testing algorithm (RITA) was employed to identify recent infections (those with a normalized optical density ≤1.5 in the LAg that met all RITA criteria) among those who tested positive for HIV and the annualized HIV incidence was estimated. RESULTS AND DISCUSSION: Out of 3053 individuals assessed, 2591 (84.9%) were HIV negative and 462 (15.1%) were living with HIV. Among these, 302 (65.4%) with stored samples available were evaluated and 73/302 (24.2%) were classified as recent infections. The annualized incidence rate estimate using a false recency rate of zero was 7.35% (95% CI 5.76% to 9.25%).
conclusionsOur results suggest that the HIV epidemic in Rio de Janeiro, Brazil, continues to disproportionately burden vulnerable populations, including MSM and TGW despite the existence and availability of effective preventive and therapeutic interventions.
