HIV and syphilis in the context of community vulnerability among indigenous people in the Brazilian Amazon.

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
backgroundContextual factors shape the risk of acquiring human immunodeficiency virus (HIV) and syphilis. We estimated the prevalence of both infections among indigenous people in nine indigenous health districts of the Brazilian Amazon and examined the context of community vulnerability to acquiring these infections.
methodsWe trained 509 health care workers to screen sexually active populations in the community for syphilis and HIV using rapid testing (RT). We then assessed the prevalence of HIV and syphilis using RT. A multivariable analysis was used to identify factors associated with syphilis infection (sociodemographic, condom use, intrusion, population mobility, and violence).
resultsOf the 45,967 indigenous people tested, the mean age was 22.5 years (standard deviation: 9.2), and 56.5% were female. Overall, for HIV, the prevalence was 0.13% (57/43,221), and for syphilis, the prevalence was 1.82% (745/40,934). The prevalence in men, women, and pregnant women for HIV was 0.16%, 0.11%, and 0.07%, respectively, and for syphilis, it was 2.23%, 1.51%, and 1.52%, respectively. The district Vale do Javari had the highest prevalence of both infections (HIV: 3.38%, syphilis: 1.39%). This district also had the highest population mobility and intrusion and the lowest availability of prenatal services. Syphilis infection was independently associated with age (odds ratio [OR] 1.04, 95% confidence interval [CI]: 1.03-1.05), male sex (OR 1.32, 95% CI: 1.14-1.52), and mobility (moderate: OR: 7.46, 95% CI: 2.69-20.67; high: OR 7.09, 95% CI: 3.79-13.26).
conclusionsThe large-scale integration of RT in remote areas increased case detection among pregnant women, especially for syphilis, in districts with higher vulnerability. Mobility is an important risk factor, especially in districts with higher vulnerability. Contextually appropriate approaches that address this factor could contribute to the long-term success of HIV and syphilis control programs.
