Brief Report: HIV Shedding in the Female Genital Tract of Women on ART and Progestin Contraception: Extended Follow-up Results of a Randomized Clinical Trial.
Trial report in Journal of acquired immune deficiency syndromes (1999), 2019. 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
backgroundProgestin contraception has been linked to higher risk of female to male sexual HIV transmission.
settingA clinical trial among HIV-infected women in Lilongwe, Malawi, randomized to initiation of depomedroxyprogesterone acetate injectable or levonorgestrel implant, and followed for up to 33 months, with the outcome of HIV shedding in the genital tract.
methodsWe compared the frequency and magnitude of HIV genital shedding before and after initiation of contraception and between study arms among women receiving antiretroviral therapy (ART). Genital HIV RNA was measured in TearFlo Strips using the Abbott RealTime HIV-1 assay.
resultsAmong 68 HIV-infected Malawian women on ART, randomization to depot medroxyprogesterone acetate compared with the levonorgestrel implant was not associated with genital shedding and neither progestin contraceptive was associated with increased HIV genital shedding, for up to 33 months after contraceptive initiation. Having detectable plasma HIV [adjusted risk ratio (RR) 10.5; 95% confidence interval (CI): 3.18 to 34.7] and detectable genital shedding before contraceptive initiation (adjusted RR 3.53; 95% CI: 1.31 to 9.47) were associated with a higher risk of detectable genital shedding after contraceptive initiation. Higher plasma efavirenz concentrations were associated with a lower risk of detectable genital shedding (adjusted RR 0.85; 95% CI: 0.73 to 0.99, per increase of 1000 ng/mL).
conclusionAmong HIV-infected women receiving ART, our results provide evidence that progestin contraception does not impact women's risk of transmission of HIV to partners. Our finding that detectable genital shedding before contraceptive initiation independently predicts shedding suggests that there may be other individual-level biological or behavioral factors that increase the risk for shedding.
