CST3 and hypertensive disorder: For prediction of all-cause mortality, the AUCs varied between 0.604 (95%CI 0.561, 0.647), 0.606 (95%CI 0.563, 0.649; Sidak p-value 0.963) and 0.606 (95%CI 0.563, 0.649; Sidak p-value 0.894) respectively using the CKD-EPI creatinine, CKD-EPI cystatin C and CKD-EPI creatinine-cystatin C equations adjusted for age, BMI, hypertension, diabetes, systolic blood pressure, prevalent renal disease and CVD, smoking history and treatment group (Figure 1).
