Continuity of long-term follow-up in patients with chronic hepatitis C after sustained virologic response following direct-acting antiviral therapy: a nationwide real-world multicenter cohort study in Japan

Within Japan's core-center network, long-term continuation after SVR is high but not universal. Follow-up was generally maintained for patients with severe comorbidities, while disengagement was more likely among those with lower perceived risk. Strengthening low-intensity, structured support for such patients may improve the continuity and equity of post-SVR care. These findings provide a foundation for optimizing post-SVR care pathways in national liver disease networks.
