Brief Report: Anal Intercourse, HIV-1 Risk, and Efficacy in a Trial of a Dapivirine Vaginal Ring for HIV-1 Prevention.
Trial report in Journal of acquired immune deficiency syndromes (1999), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesTo describe receptive anal intercourse (RAI) behaviors and correlates in a cohort of sub-Saharan African women, evaluate the association of RAI with HIV-1 risk, and evaluate whether the HIV-1 prevention efficacy of a dapivirine vaginal ring differs among women who reported RAI.
designSecondary analysis of the MTN-020/ASPIRE trial, a randomized, double-blind, placebo-controlled trial evaluating a dapivirine vaginal ring for HIV-1 prevention.
methodsAt enrollment and month 3, women reported RAI in the prior 3 months in audio computer-assisted self-interviews. We evaluated associations between RAI and participant characteristics with χ and t-tests adjusted for study site. Cox proportional hazards models stratified by study site tested the association of RAI with HIV-1 acquisition and effect modification by RAI.
resultsEighteen percent of women reported any RAI at enrollment and/or month 3, with a median of 2 (interquartile range: 1-4) RAI acts in the prior 3 months, accounting for 1.5% of total sex acts. RAI prevalence was higher among women with lower educational attainment and those reporting transactional sex. In adjusted models, RAI was not associated with HIV-1 acquisition (aHR: 0.93, 95% CI: 0.57 to 1.54). The ring reduced HIV-1 risk by 27% (95% CI: -5 to 49) among women reporting no RAI and by 18% (95% CI: -57 to 57) among women reporting any RAI (interaction P-value = 0.77).
conclusionsRAI was modestly infrequent and was not associated with reduced HIV-1 protection from the ring, suggesting that, in populations with rates of RAI similar to this cohort, RAI may not appreciably reduce the population-level impact of the dapivirine vaginal ring.
