1 · What the graph read from it

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.

2 · The registry

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

The prevalence of hepatitis C virus (HCV) infection in Taiwan was approximately 4% a decade ago, much higher than the worldwide average. This study aimed to assess the HCV burden among 4 million voluntary blood donors after 2 decades of prevention and treatment policies. We retrieved screening results for anti-HCV and HCV RNA from the Database for Evaluating Voluntary Taiwanese Eligible Donors. First-time blood donors who donated blood after 1999 and repeat donors who donated blood more than once between 2013 and 2017 were included to estimate HCV prevalence and incidence, respectively. The Cox proportional hazards model was used to estimate hazard ratios. Geographic variation in HCV prevalence and incidence in 364 townships was also analyzed. The prevalence study included 3,656,598 first-time donors. The overall crude prevalence of anti-HCV decreased from 15.5 to 4.5 per 1,000 donors between 1999 and 2017. Younger birth cohorts had a significantly lower prevalence of anti-HCV. The majority of townships (64.3%) in Taiwan showed a significantly decreased prevalence. The incidence study included 1,393,014 repeat donors followed for 3,436,607 person-years. Ninety-eight donors seroconverted to HCV RNA positivity, resulting in an HCV incidence of 2.9 per 100,000 person-years. Donors living in townships where HCV RNA prevalence was greater than 2 per 1,000 had at least 2.5-fold greater risk of new HCV infection.
