(A) Propensity-matched survival stratified by surgical approach: this figure depicts the Kaplan–Meier overall survival estimates of the open group (dashed line) versus the VATS group (solid line) using the propensity-matched data. (B) Propensity-matched recurrence-free survival stratified by surgical approach: this figure depicts the Kaplan–Meier recurrence-free survival estimates of the open group (dashed line) versus the VATS group (solid line) using the propensity-matched data. Tick marks represent censored subjects. VATS: video-assisted thoracoscopic surgery.
