Kaplan–Meier curves for OS and PFS by pre-therapeutic nutritional indicators in elderly RC patients. BMI survival curves of OS (A) and PFS (B); PNI survival curves of OS (C) and PFS (D); GNRI survival curves of OS (E) and PFS (F); PAR survival curves of OS (G) and PFS (H). 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.
