Factors associated with serum calcification propensity T50 (n = 472) in the study cohort in a hierarchical regression model [dependent variable T50, Model 1 includes age, sex, calcium, phosphate, magnesium and albumin (change in F: P < .001), Model 2 further includes zinc (change in F: P = .007)], shown with regression coefficients (beta) and levels of significance (P-value; bolded if P < .05).
