Natural history of major complications in hepatitis C virus-related cirrhosis evaluated by per-rectal portal scintigraphy

Figure 1 Flow of monitoring, group I, PSI ≤ 10%; group II, 10% < PSI < 30%; group III, 30% ≤ PSI. LC-C, HCV-related cirrhosis; Child A, Child-Pugh stage A; PSI, portal shunt index.

Figure 2 The probability of each life-threatening complication. A: The cumulative incidence rate of HCC (n = 108). B: The cumulative progression rate of Child A to B (n = 107). C: The cumulative progression rate of esophagogastric varices (n = 109). The continuous line shows group I (PSI ≤ 10%); the large dotted line shows group II (10% < PSI < 30%); and the small dotted line shows group III (30% ≤ PSI). Child A, Child-Pugh stage A; PSI, portal shunt index; pts, patients; GI, group I; GII, group II; GIII, group III; NS, not significant.
