Results of stepwise logistic regression analyses utilising the Bayesian information criterion (BIC).

Odds ratios represent the odds of a primary composite cardiac outcome at five years (n = 59880) and nine years (n = 22028) after initial serum phosphate measurement. Serum albumin was not retained during the stepwise approach at 5 years. CI = confidence interval. P values <0.05 were deemed significant. Receiver operating characteristic curve (ROC C) statistics were 0.78 and 0.79 for the five-year and nine-year reviews, respectively.
