Kaplan-Meier survival curves. (a) Kaplan-Meier survival curve from the initial diagnosis to death in patients with non-honeycomb formation (N = 24) versus those with honeycomb formation (N = 16). Patient characteristics and prognosis were not significantly different between the two groups (log rank, P = 0.565). (b) Kaplan-Meier survival curve from the time of honeycomb formation to death in the group with honeycomb formation showed a median survival time of 3.2 years and 5-year survival rate of 49.8%
