Towards a Better Understanding of HIV Prevention Knowledge Among Latino MSM: A Latent Class Analysis Study.
Article in AIDS and behavior, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Latino men who have sex with men (LMSM) are disproportionately affected by HIV in the United States. Despite advances in HIV prevention options, LMSM have inequitably low access to knowledge about HIV, HIV testing, and pre-exposure prophylaxis (PrEP), contributing to disparities in prevention service use. We first identified subgroups of LMSM (N = 290) based on their patterns of knowledge related to HIV prevention by using latent class analysis. Secondly, following a three-step logistic regression procedure, we examined differences in class composition by demographics. Lastly, we evaluated the relationship between class membership and HIV prevention behaviors (e.g., PrEP engagement, HIV testing, and sexual behavior that could lead to HIV acquisition), using Lanza's method to estimate the probability of class membership. We identified three classes among LMSM based on HIV knowledge: Class 1: HIV/PrEP Experts (n = 112), Class 2: Moderate HIV/PrEP Knowledge (n = 140), and Class 3: HIV Knowledge Only (n = 38). We found no significant association between class membership and demographics (education, income, race, nativity). Class membership was associated with prevention behaviors: HIV testing (χ
