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
backgroundMen who have sex with men (MSM) with HIV are disproportionately affected by human papillomavirus (HPV) and related diseases. We assessed HPV vaccine effectiveness (VE) against anal HPV among MSM with HIV.
methodsDuring 2018-2023, residual anal specimens from MSM with HIV, aged 18-45 years, attending sexual health clinics in three U.S. cities were collected and tested for HPV. Demographic and vaccination information were obtained from clinic records or immunization registries. Timing of vaccination relative to HIV acquisition was unknown. Log-binomial regression was used to calculate adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for associations between vaccination (≥1 dose) and quadrivalent vaccine (4vHPV)-type infection, adjusting for city. Models were stratified by age group (18-26, 27-45 years). VE was calculated as (1-aPR) x 100.
resultsAmong 224 persons aged 18-26 years, 54% were vaccinated. Compared with unvaccinated persons, 4vHPV-type prevalence was lower in those vaccinated at age <18 (aPR=0.31, 95% CI:0.14-0.72, VE=69%) and ≥2 years before specimen collection (aPR=0.54, 95% CI:0.31-0.92, VE=46%). Among 700 persons aged 27-45 years, 17% were vaccinated. Compared with unvaccinated persons, 4vHPV-type prevalence was lower in those vaccinated at ages 18-26 (aPR=0.63, 95% CI:0.45-0.89, VE=37%) and ≥2 years before specimen collection (aPR=0.63, 95% CI:0.46-0.86, VE=37%).
conclusionsWhile timing of vaccination relative to HIV acquisition was unknown, we found significant VE against prevalent HPV infection in adult MSM with HIV. Within each age group, VE was higher with younger age at vaccination.
