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 and aim: Hepatitis C virus (HCV) infection is one of the major global health challenges, leading to a significant increase in rates of hepatic fibrosis, cirrhosis and hepatocellular carcinoma. A comprehensive nationwide survey of trends in prevalence and associated factors could facilitate preventive behavioral interventions. Herein, we sought to determine prevalence, diagnosis, treatment, and risk factors for HCV infection in the general United States (US) population. Methods: This was a secondary analysis of the publicly available data from the US National Health and Nutrition Examination Survey (NHANES). The prevalence of HCV-RNA-positive (HCV-RNA+) was weighted using patient serum sample data collected from 1999 to 2018. A propensity score matching model was used due to the imbalance in the number of HCV-RNA+ and HCV-RNA-negative (HCV-RNA-) patients. Matched variables included gender, age, educational level, marital status, language, household size, alcohol consumption, smoking, number of family members and family income to poverty ratio. Results: The weighted prevalence of HCV-RNA+ was 1.11% (95% confidence interval (CI): 1.02-1.20), 1.58% (95% CI: 1.42-1.74) for men and 0.67% (95% CI: 0.57-0.77) for women aged 20 years or older in the US from 1999 to 2018. The weighted prevalence of HCV-RNA+ increased from 0.87% (95% CI: 0.62-1.12) in 2013-2014, 0.95% (95% CI: 0.68-1.22) in 2015-2016 to 1.00% (95% CI: 0.72-1.28) in 2017-2018, respectively. In propensity-matched analysis, patients with HCV-RNA+ were more likely to be non-Hispanic black, and have had drug use and blood transfusions. Meanwhile, the weighted diagnostic and treatment rates were 56.27% (95% CI: 50.90-61.64) and 35.40% (95% CI: 27.64-43.16) from 1999 to 2018, respectively. Conclusions: Active HCV infection rate increased between 2013 and 2018, varied by demographic and risk variables. In the direct-acting antiviral era, affordable treatment and universal screening have the potential to improve overall national health.
