A: Kaplan-Meier analysis of the overall survival (OS) in microvascular invasion (MVI) positive and MVI negative patients with a tumor diameter 2-5 cm; B: In the group with a tumor diameter of 2-5 cm, Kaplan-Meier analysis of the OS in receiving MVI positive anatomic resection (AR) and non-anatomic resection (NAR) patients; C: In the group with a tumor diameter of 2-5 cm, Kaplan-Meier analysis of the OS in receiving AR and NAR patients with MVI negative. D: Kaplan-Meier analysis of the OS in MVI positive and MVI negative patients with a tumor diameter of less than 2 cm.
