Construction and validation of a nomogram in TCGA. The best cut-off value of LRRC15 (A). The LRRC15 expression level was divided into high and low groups with the best cut-off value. The K-M curve shows that the LRRC15-high group had a shorter OS, P < 0.05 (B). Multivariate Cox regression forest plot based on the TCGA training set (n = 260). C-index = 0.65 (0.6, 0.7) (C). The nomogram based on LRRC15 expression levels and clinicopathological factors, including age and FIGO stage (D). Calibration curves for the nomogram predicting 1-, 3-, and 5-year survival in OV patients from the TCGA verification set (n = 111) (E)
