Prognostic impact of adjuvant chemotherapy and the geriatric nutritional risk index (GNRI) in rectal cancer patients with pathological lymph node metastasis. a Kaplan–Meier curve for overall survival (OS) in patients with pathological lymph node metastasis according to adjuvant chemotherapy (n = 40). OS was not significantly different between adjuvant (+) (n = 34) and adjuvant (−) (n = 6) (p = 0.26, log-rank test). b Kaplan–Meier curve for disease-free survival (DFS) in rectal cancer patients with pathological lymph node metastasis according to adjuvant chemotherapy (n = 40). DFS was not significantly different between adjuvant (+) (n = 34) and adjuvant (−) (n = 6) (p = 0.29, log-rank test). c Kaplan–Meier curve for OS in patients with pathological lymph node metastasis according to GNRI levels (n = 40). OS was significantly higher in patients with a high GNRI (n = 24) compared with those with a low GNRI (n = 16) (p = 0.033, log-rank test). d Kaplan–Meier curve for DFS in patients with pathological lymph node metastasis according to GNRI levels (n = 40). DFS was significantly higher in patients with a high GNRI (n = 24) compared with those with a low GNRI (n = 16) (p = 0.032, log-rank test)
