Syphilis prevalence and correlates of infection among Venezuelan refugees and migrants in Colombia: findings of a cross-sectional biobehavioral survey.
Article in Lancet regional health. Americas, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Background: Population-based estimates of syphilis prevalence are critical to informing public health response. We aimed to measure syphilis prevalence among Venezuelan refugees and migrants in Colombia to inform public health programming. Methods: Between July 2021 and February 2022, we surveyed 6221 adult Venezuelan refugees and migrants in four cities in Colombia using respondent-driven sampling (RDS). Participants completed a survey and dual-rapid HIV/treponemal syphilis screening. Confirmatory laboratory-based rapid plasma reagin testing was conducted on whole blood samples. Active syphilis infection was defined as RPR titer ≥ 1:8 and no self-reported syphilis treatment. We used multivariable regression models to identify associations with active syphilis infection among subgroups by gender and history of pregnancy (cisgender men n = 2123, cisgender women n = 4044, transgender/nonbinary people n = 47, pregnant women n = 150). Findings: Population (RDS-weighted) prevalence of laboratory-confirmed syphilis was 5.1% (95% CI: 4.6-5.6). Syphilis prevalence was 5.8% (weighted) among men; lifetime sexually transmitted infections (STI) diagnosis, same-sex relationships, HIV infection, and partner number were independently associated with syphilis infection. Syphilis prevalence was 4.6% (weighted) in women; correlates of infection included: lifetime STI diagnosis, food insecurity, current engagement in sex work, current pregnancy, any unsafe night in Colombia, irregular migration status, and no healthcare utilization in Colombia. 14.9% (unweighted) of transgender participants had syphilis infection; correlates of infection included partner number and HIV infection. The prevalence of syphilis was 9.0% (weighted) among pregnant women, which was associated with lifetime STI diagnosis. Interpretation: Syphilis among Venezuelans in Colombia is high. Correlates of infection are distinct among demographic groups, spanning sexual and social vulnerabilities, suggesting tailored public health strategies.
