Figure 2 Kaplan-Meier analysis of recurrence-free survival and overall survival before and after propensity score matching or inverse probability of treatment weighting. A: Recurrence-free survival (RFS) before propensity score matching and inverse probability of treatment weighting; B: RFS after propensity score matching; C: RFS after inverse probability of treatment weighting; D: Overall survival (OS) before propensity score matching and inverse probability of treatment weighting; E: OS after propensity score matching; F: OS after inverse probability of treatment weighting. PCT: Postoperative combined therapy; PSM: Propensity score matching; IPTW: Inverse probability of treatment weighting; RFS: Recurrence-free survival; OS: Overall survival; IQR: Interquartile range; FU: Follow up; HR: Hazard ratio; CI: Confidence interval; NA: Not available.
