The time-ROC of nutritional indicators in elderly RC patients. (A, B) the time-ROC of BMI on OS and PFS (1 year, 3-year, and 5-year); (C, D) the time-ROC of PNI on OS and PFS (1 year, 3-year, and 5-year); (E, F) the time-ROC of GNRI on OS and PFS (1 year, 3-year, and 5-year); (G, H) the time-ROC of PAR on OS and PFS (1 year, 3-year, and 5-year); (I, J) the time-ROC of NNPI on OS and PFS (1 year, 3-year, and 5-year). time-ROC the time-dependent receiver operating curve; RC rectal cancer; OS overall survival; PFS progression-free survival; BMI body mass index; PNI the prognostic nutritional index, GNRI the geriatric nutrition risk index; PAR platelet-albumin ratio.
