The Cox regression models. ZC3H12D was beneficial to the overall survival of patients in both a univariate and b multivariate Cox regression models. c Nomogram to predict the 1-y, 3-y and 5-y overall survival of LUAD patients. A nomogram was built based on multivariate Cox proportional hazards analysis to predict the X-year overall survival, calculating the risk by the points associated with each factor. A higher score indicated a higher risk of death. Calibration curve for the OS nomogram model of ZC3H12D. d A red line represented the 1-y observed nomograms, an orange line represented the 3-y observed nomograms, a blue line represented the 5-y observed nomograms and a gray diagonal line represents the ideal nomogram. The nomogram predicting 1-year OS was relatively more accurate than the nomogram predicting 3-year OS or 5-year OS of LUAD patients
