Fig. 4 — Nomogram model for LACC patients to predict the 2- and 3-year OS. PLN indicates positive (1) or negative (0) pelvic lymph nodes. PALN indicates positive (1) or negative (0) para-aortic lymph nodes. To use, find patient’s age on age axis, then draw straight line upward to points axis to determine how many points patient receives for age and do this again for other variable axes. The total points predicted on the bottom scale was calculated by summing all points on the scale for each variable to estimate the probabilities of 2-year and 3-year OS rates by plotting a vertical line. OS: Overall survival; SCC: squamous cell carcinoma; AC: adenocarcinoma; ASC: adenosquamous carcinoma; PLN: pelvic lymph node; PALN: para-aortic lymph node; HGB: hemoglobin
