Community-based interventions to improve hepatitis C linkage to care among people with substance use disorders in Southwest Virginia: a pragmatic sequential cohort study.
Article in Research connections, 2026. 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
In 2024, the reported hepatitis C virus (HCV) case rate in Roanoke City was nearly three times the rate of the state of Virginia, reflecting the disproportionate impact of the opioid epidemic in the region. Despite highly effective direct-acting antiviral therapies, substantial barriers to linkage to care (LTC) persist among individuals with substance use disorders (SUDs). While prior studies suggest that patient navigation and financial support may improve LTC, evidence from rural and underserved settings remains limited. This study aims to evaluate community-based interventions designed to improve HCV LTC among individuals with SUD in Southwest Virginia. We conducted a pragmatic, non-randomized, sequential cohort pilot study to evaluate the impact of iteratively refined community-based interventions on LTC. A total of 60 adults with detectable HCV RNA and SUD were enrolled sequentially into four cohorts (control and three intervention groups). All participants received peer support; intervention components were modified across cohorts to address observed barriers to care. The primary outcome was attendance at an outpatient HCV visit within 180 days of enrolment. LTC was 3/15 (20%) in both the control group and Intervention 1, increasing to 6/15 (40%) in Intervention 2 and 11/15 (73%) in Intervention 3. Exploratory analyses demonstrated significantly higher attendance in Intervention 3 than in the control group (73% vs. 20%,
