Continuous data are expressed as mean ± SD or median [IQR], and categorical data are shown as number (percentage). RATS, robot-assisted thoracoscopic surgery; VATS, video-assisted thoracoscopic surgery; SD, standard deviation; IQR, interquartile range; ICU, intensive care unit; LN, lymph node; IPR, incomplete pathological response; MPR, major pathological response; pCR, pathological complete response; yP, yield pathological.
