None of the variables, including gender (male vs. female), age (< 47 vs. ≥47 years), BMI (< 24 vs. ≥24 kg/m2), diabetes history (no vs. yes), CVD history (no vs. yes), mean SBP (< 140 vs. ≥140 mmHg), RKF loss in the first year (no vs. yes), mean total weekly Kt/V score (< 1.7 vs. ≥1.7), mean blood HGB (< 110 vs. ≥110 g/L), mean serum albumin (< 35 vs. ≥35 g/L), phosphate-binding use (no vs. yes) as well as RASi medication (no vs. yes) significantly modified the association between serum phosphorus time in range in the first PD year and all-cause mortality (all P-interactions > 0.05) (Fig. 3). This evidence concerns the gene ALB and diabetes mellitus.
