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) has significantly impacted people with human immunodeficiency virus (HIV). Harm reduction programs, changing transmission patterns, and direct-acting antivirals (DAAs) have profoundly altered HIV/HCV coinfection trends. This study evaluates HCV prevalence among people with HIV in Spain over 2 decades.
methodsWe conducted 9 cross-sectional studies (2002-2023) in 39-43 centers. Sampled individuals were randomly sampled from people with HIV actively followed up at these centers, with proportional allocation. Main outcomes included the prevalence of anti-HCV antibody and active HCV infection (HCV RNA--positive result).
resultsThe reference population ranged from 31 800 to 47 006, with sample sizes of 1260-1867. HIV transmission patterns shifted from 2002 to 2023, with injection drug use decreasing from 55% to 21% and the proportion of men who have sex with men increasing from 17% to 46%. HCV seroprevalence fell from 60.8% to 27.4%, and active infection from 46.3% to 0.9%. In the DAA era (2015-2023), active HCV infection dropped by 100% in heterosexuals, 94% in people who inject drugs, and 71% in men who have sex with men. Treatment uptake increased from 23% in 2002 to 99% by 2023 with all-oral DAAs. The prevalence of cirrhosis among active HCV cases peaked at 23.1% in 2015 but fell to 0% by 2021. Among those achieving sustained virologic response, cirrhosis prevalence was 20.4% in 2023.
conclusionsHIV/HCV coinfection has drastically declined in Spain, with active HCV infection prevalence <1% since 2021. DAAs were pivotal in this achievement. However, cirrhosis remains a concern among those with sustained virologic response. Ongoing surveillance and prevention efforts are essential to sustain these gains and address residual risks.
