Table 1 Characteristics of the participants. The data are presented as medians (interquartile range [IQR]) and n (%). *: the Mann–Whitney U test was employed for the purpose of comparing two groups. Regional lymph node metastasis: Regional lymph node metastasis corresponds to N1 and N2 stages in the N staging system. Chemoradiotherapy: the patient underwent radiotherapy and chemotherapy. Robotic: Da Vinci Surgical Robot. HGB: hemoglobin; ALB: albumin; LARS: low anterior resection syndrome; CI: confidence interval.
