Colorectal cancer screening to identify undiagnosed hepatitis C in an Austrian cohort.
Article in Central European journal of public health, 2025. 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
objectivesHepatitis C virus (HCV) infection remains a significant public health concern despite the introduction of direct acting antiviral agents. To reach the World Health Organization (WHO) goal of eliminating viral hepatitis as a public health threat by 2030, adequate screening strategies and early diagnosis are crucial. This study aimed to determine the prevalence of HCV infection in an Austrian cohort and assess the feasibility of incorporating HCV screening into colorectal screening programmes.
methodsThe study enrolled 1,894 asymptomatic individuals during a colorectal screening programme with a mean age of 57 (± 7 years) years. Sera of the participants were screened for HCV-specific antibodies, and blood samples of individuals with detectable HCV-specific antibodies were tested by the polymerase chain reaction (PCR) to confirm a chronic HCV infection. Furthermore, we evaluated the characteristics of these individuals including their anthropometrics, biomarkers, and liver-specific information such as those obtained with a fibroscan.
resultsWe found that 14 (0.74%) of the participants had detectable levels of HCV-specific antibodies, with 6 (0.32%) individuals being newly diagnosed with a chronic HCV infection. One of the 6 patients showed signs of liver cirrhosis. The newly diagnosed individuals included 4 cases of HCV genotype 1a and 2 cases of 1b.
conclusionOur study highlights the importance of screening for HCV infection in asymptomatic individuals, not only for those at risk of HCV exposure or with elevated liver enzymes. Incorporating HCV screening into colorectal screening programmes could be an effective strategy for increasing the rate of HCV diagnosis, thereby improving public health outcomes. Further investigation is needed regarding cost-effectiveness and strategies to reach individuals who have no access to screening programmes or do not adhere to regular preventive screenings.
