Kaplan-Meier cumulative incidence function: time to incident hepatocellular carcinoma (HCC) by FIB-4 category. Kaplan-Meier cumulative incidence curves display time to incident HCC diagnoses, stratified by FIB-4 category (low, intermediate, and high). To reduce the possibility of reverse causality, follow-up time began one year after baseline. Therefore, time 0 on the x-axis is equivalent to one year post-baseline.
