Cumulative risk of all-cause death according to urinary solute tertiles. (a) Kaplan-Meier survival curves are displayed according to tertiles of urinary sodium concentration (U_Na) at baseline. Patient grouping: solid line indicates high U_Na tertile patients; dashed line indicates intermediate U_Na tertile patients; dotted line indicates low U_Na tertile patients. P value Log-rank test < 0.001. (b) Kaplan-Meier survival curves are displayed according to tertiles of urinary potassium concentrations (U_K) at baseline. Patient grouping: solid line indicates high U_K tertile patients; dashed line indicates intermediate U_K tertile patients; dotted line indicates low U_K tertile patients. P value Log-rank test < 0.001. (c) Kaplan-Meier survival curves are displayed according to tertiles of urine to plasma creatinine concentration ratio (U : P_creat) at baseline. Patient grouping: solid line indicates high U : P_creat tertile patients; dashed line indicates intermediate U : P_creat tertile patients; dotted line indicates low U : P_creat tertile patients. P value Log-rank test < 0.001.
