Fig. 4: Number of office visits for identified HCV by race/ethnicity over study period.
From: Sociodemographic disparities in Hepatitis C care utilization and testing in the United States
Points show the survey-weighted totals of visits for each race/ethnicity across periods; error bars represent 95% confidence intervals derived from survey-weighted variance estimation. Changes over time were assessed within each race/ethnicity using two-sided, design-adjusted Wald F tests comparing pre- and post-periods. Total visits increased significantly after approval of direct-acting antivirals among White patients (p = 0.005) but not among Black (p = 0.220) or Hispanic/Latino patients (p = 0.08). n denotes unweighted visit counts (non-Hispanic White n = 32–166; non-Hispanic Black n = 9–58; Hispanic/Latino n = 10–32).
