Comparison of ROC curves for fully adjusted and univariate cox regression models in asessing survival status using In (Dietary Vitamin K intake). The ROC curves compare the performance of the Multivariate Cox Model (Adjusted II model, adjusted for Age, sex, race, educational level, BMI category, alcohol consumption status, HEI-2020 score, dietary supplement use, total cholesterol, triglycerides, hypertension history, diabetes history, total energy intake, cardiovascular disease and smoking status.) and the Univariate Cox Model in predicting survival based on natural log-transformed dietary vitamin K intake without additional covariates.
