Tenofovir Gel for Prevention of Herpes Simplex Virus Type 2 Acquisition: Findings From the VOICE Trial.
Trial report in The Journal of infectious diseases, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
backgroundGenital infection with herpes simplex virus type 2 (HSV-2) is common and increases risk of human immunodeficiency virus (HIV) transmission and acquisition. Pericoital use of tenofovir (TFV) gel provided protection from HSV-2 acquisition in the CAPRISA 004 study.
methodsWe measured estimate of effect of vaginal TFV 1% gel in preventing HSV-2 acquisition among women in VOICE, randomized, double-blinded, placebo-controlled trial assessing daily use of oral and vaginal TFV for HIV-1 preexposure prophylaxis. The TFV level in plasma at the first quarterly visit was used as a measure of gel use.
resultsOf 566 participants at risk for HSV-2 acquisition, 532 (94%) had first-quarter plasma TFV and end-of-study HSV-2 serologic data available. Over a follow-up period of 501 person-years, 92 incident cases of HSV-2 acquisition occurred: 77 were in women with no TFV detected in plasma, and 15 occurred in women with TFV detected in plasma (incidence, 20.6 cases/100 person-years [95% confidence interval [CI], 16.2-25.7] vs 11.9 cases/100 person-years [95% CI, 6.6-19.6], respectively). TFV detection in plasma was associated with a trend toward a reduced risk of HSV-2 seroconversion, with an unadjusted hazard ratio (HR) of 0.59 (95% CI, .34-1.02; P = .060) and a HR adjusted for site, age, having ≥2 male sex partners in the past 3 months, use of hormonal contraception, having anal sex in the past 3 months, and HIV status of 0.60 (95% CI, .33-1.08; P = .086).
conclusionsDetection of TFV in plasma among TFV gel users was associated with a trend toward a reduced risk of HSV-2 acquisition, after controlling for sexual behavior and HIV-1 acquisition.
