Prevalence and risk factors of active hepatitis C infection among at-risk migrant populations in Madrid, Spain, 2019 to 2023.

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
BACKGROUNDHepatitis C virus (HCV) microelimination among at-risk migrants supports global elimination goals.AIMTo evaluate risk factors, prevalence and trends of active HCV infection among at-risk migrants screened for HCV in Madrid from 2019-23.METHODSAt-risk migrants (born outside Spain, living in country < 10 years regardless of legal status), were screened for HCV via mobile units with rapid antibody testing, and confirmed by RNA testing. Recruitment of this convenience sample focused on migrant centres, shelters, harm reduction centres and social service sites. Primary outcome was active HCV prevalence. Risk factors analysed included origin, alcohol use, no stable income, drug use and sexual behaviour. Data were analysed using general linear models with negative binomial distribution and p values adjusted for multiple comparisons (q values).RESULTSAmong 2,288 migrants, 6.5% (149/2,288) had anti-HCV antibodies, 47.0% (70/149) of whom tested positive for HCV-RNA; 81.4% (57/70) began antiviral therapy. Overall prevalence of active HCV infection was 3.1% (70/2,288). Injection drug use (non-active vs never used (aIRR: 7.3; 95% CI: 2.7-12.7) and active (aIRR: 14.7; 95% CI: 6.7-32.1)), European origin (vs non-European; aIRR: 5.8; 95% CI: 2.7-12.7) and alcohol misuse (vs no misuse; aIRR: 1.8; 95% CI: 1.1-2.9) were main risk factors. Prevalence showed no significant change during 2019-23 in the overall population and across risk groups.CONCLUSIONAt-risk migrants screened in Madrid had a high prevalence of active HCV infection. This is higher than reported estimates for the general Spanish population and supports the need to enhance targeted HCV prevention, screening and treatment strategies among migrant populations.
