Identifying Syndemic Factors and Their Effect on HIV Sexual Risk Behavior Among Gay, Bisexual and Other Men Who Have Sex with Men in Vancouver, Montreal and Toronto.

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
We set out to identify syndemic factors associated with HIV sexual risk behavior among HIV-negative gay, bisexual and other men who have sex with men (GBM), and examine associations between syndemic factors and HIV sexual risk behaviors using models of co-occurring epidemics. We used baseline data from 1571 sexually active GBM from the Engage Cohort study, recruited using respondent-driven sampling in Montreal, Toronto, and Vancouver. We explored associations between potential syndemic factors and HIV sexual risk behavior, and used oblique component analysis to reduce the number of variables. Path analysis and logistic regression with interaction terms were used to evaluate the association of syndemic factors with HIV sexual risk behavior. In the mediation model, childhood sexual abuse (CSA) was associated with HIV sexual risk behavior (total effect: c = 0.14, 95% CI 0.06-0.21). This effect was mediated by any intimate partner violence (IPV), transactional sex, polysubstance use, and sexual compulsivity. We observed a multiplicative interaction between CSA and transactional sex: GBM with a history of both had 14 times the odds of HIV sexual risk behavior (aOR of 14.0 95% CI 5.6-35.2) compared to those with neither. The appropriate application of a syndemic approach allowed a nuanced assessment of syndemic factor associations with HIV sexual risk behavior. IPV, transactional sex, sexual compulsivity, and polysubstance use mediated the effect of CSA on HIV sexual risk behavior. Additionally, we found a significant multiplicative interaction between CSA and transactional sex.
