Patient characteristics according to sex-stratified tertiles of predialysis copeptin levels.

Continuous variables are represented as mean ± SD, skewed variables as median and interquartile range (IQR) and categorical variables as number and percentage within tertile. The number of the included patients is indicated.* P-value indicates differences between tertiles.** Post-hoc test of age showed a significant difference between tertile 1 and 2 (p = 0.02) and between tertile 1 and 3 (p = 0.03).Abbreviations: BMI: body mass index; DBP: diastolic blood pressure; F: females; M: males; MAP: mean arterial blood pressure; NT-proBNP: N-terminal pro-brain natriuretic peptide; SBP: systolic blood pressure.Patient characteristics according to sex-stratified tertiles of predialysis copeptin levels.
