Identification of risk profiles among persons attending a sexually transmitted infection clinic in Estonia.
Article in PloS one, 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
backgroundWhile generalized STI prevention guidelines exist, individuals present with diverse interconnecting risk behaviors and needs. This cross-sectional study used latent class analysis to identify distinct behavioural profiles among men and women undergoing STI testing and to examine their potential implications for STI prevention.
methodsData was collected by questionnaire from 1171 individuals seeking STI testing at the North Estonia Medical Centre between August 2022 and October 2023. Latent class analysis was applied to identify subgroups based on eight relevant STI risk variables. Separate models were fitted to men and women.
resultsWe propose three latent classes for both sexes. Among men, three classes were identified: "multiple partners; elevated behavioural risk" (62.4%); "predominantly monogamous; fewer behavioural risk indicators" (21.9%); and, "multiple partners; previous STI history; concentrated co-occurring risk" (15.7%). Women were categorised as follows: "new sexual partners; inconsistent condom use" (41.6%); "multiple partners; previous STI history; concentrated behavioural risk" (30.2%); and, "predominantly monogamous; possible partner-related exposure" (28.2%). The identified profiles demonstrated heterogeneity in sexual behaviour, condom use, prior STI history, and substance use across STI clinic attendees.
conclusionsThe identified behavioural profiles highlight how co-occurring risk factors cluster within STI clinic populations and may help contextualise prevention discussions alongside individualized clinical assessment. These findings may support prevention discussions addressing partner communication, condom use, substance use, IPV awareness, and partner notification.
