Nomogram construction and validation. The nomogram model (a) based on POSTN expression levels and clinicopathological characteristics were constructed to predict OS of CC patients underwent radical radiotherapy. Calibration curves of the nomogram for predicting 1- (b), 3- (c), and 5-year (d) OS. The C-index of the nomogram and other clinicopathological characteristics (e). Kaplan-Meier survival analysis (f, g), 1-year (h, i), 3-year (j, k), and 5-year (l, m) ROC analysis for nomogram from the TCGA database and our center. OS, overall survival; CC, cervical cancer; C-index, concordance index; ROC, receiver operating characteristic; TCGA, the cancer genome atlas database.
