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
objectiveTo analyze the statistical association of trust in a sexual partner and inconsistent condom use among men who have sex with men in Brazil.
methodsData came from a nationwide biological and behavioral surveillance cross-sectional study conducted in 2016 across 12 Brazilian cities with 4,176 men who have sex with men, utilizing respondent-driven sampling. This analysis focused on 2,010 men who have sex with men. We analyzed the data using Poisson Regression with robust standard errors. Weights and design were incorporated.
resultsAlmost half of the men who have sex with men had inconsistent condom use during their last anal intercourse (48.9%, n=880). Inconsistent condom use was more prevalent among men who have sex with men who said they accept having sex without using a condom when trusting their sexual partner (84.2%, p<0.0001). Trust in a sexual partner had a strong association with inconsistent condom use during last anal intercourse among all men who have sex with men (adjusted prevalence ratio (PRa) of 1.73, 95%CI 1.25-2.40, p<0.0001). This association remains statistically significant in our stratified analysis among single/separated/widowed men who have sex with men (PRa=1.93, 95%CI 1.44-2.60, p<0.0001) and among men who have sex with men who are married/live together (PRa=1.31, 95%CI 1.11-1.77, p=0.045), indicating that trust can be experienced in different relationship contexts, not only with main or steady partners, such as a husband or boyfriend.
conclusionTrust plays an important role in sexual behavior among men who have sex with men, and it is related to a higher prevalence of inconsistent condom use. Since the HIV epidemic among men who have sex with men in Brazil appears to be growing, future prevention strategies have to consider this and incorporate trust into counseling actions because trusting relationships also carry a risk of HIV infection.
