2.5. Nomogram and Predictive Performance Evaluation

Cox regression analysis, both univariate and multivariate, was conducted to determine if LINC01615 might be an independent prognostic factor. Additionally, nomogram [28] and calibration plots for the predicting 1-year, 3-year, and 5-year OS were constructed using the “rms” package. The calibration plots analyzed visually by mapping the predicted probability from the nomogram to the actual rates. The bootstrap approach was used to calculate 1000 resamples. Additionally, receiver operating characteristic (ROC) curves were utilized to determine the predictive accuracy in survival and diagnosis prediction.
