Sociodemographic risk factors for hepatitis C virus infection in a prospective cohort study of 257 persons in Canada who inject drugs.

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: Approximately 60% of incident hepatitis C virus (HCV) infections are due to intravenous drug use; therefore, understanding the socio-demographics of people who inject drugs (PWID) is necessary to achieve HCV elimination. Methods: In this prospective cohort study of PWID, we determined patients' baseline HCV antibody, hepatitis B virus (HBV), and HIV serological status. HCV antibody- negative (anti-HCV-negative) cases were followed for seroconversion (median 17 mo with q3m testing) as part of a larger study to develop a vaccine for HCV. An interviewer-administered baseline questionnaire completed with all patients evaluated socio-demographic and clinical characteristics. Results: We tested 257 PWID (median age 40 [range 49-31]y, 81% men, 63% Caucasian, 28% Indigenous). Of these, 28% were positive for HCV antibodies (anti-HCV-positive) (median age 42 [range 49-36]y, 74% men, 69% Caucasian, 29% Indigenous). Compared with anti-HCV-negative PWID, anti-HCV-positive PWID reported injecting more morphine and hydromorphone, using more hydromorphone via non-injection routes, and were more likely to be enrolled in methadone programs. More than 60% reported previous HCV testing, but recent testing (<2 y) was more frequent in the anti-HCV-negative group ( Conclusions: In this prospective study, differences in age, timing of HCV testing and risk behaviours were found between anti-HCV-positive and anti-HCV-negative groups.
