Although MVI independently impaired RFS before balancing the confounder — tumor size, it was ultimately identified as a potential but not an independent risk factor for recurrence in sHCC patients after PSM.
Figure 1. Flowchart of the study population. (a) the workflow of our study population before and after propensity score matching (PSM); (b) the frequency of MVI stratified by tumor size.
Figure 2. The Kaplan-Meier curves in terms of MVI statuses and grades. (a) and (b) were stratified by MVI statuses and grades in the Pre-PSM subgroup, respectively; (c) and (d) were stratified by MVI statuses and grades in the Post-PSM subgroup , respectively.
