Model 1 is adjusted for age, gender, ethnic, sector of dialysis provider; Model 2 is adjusted for all confounders in model 1 and dialysis vintage, Kt/V, normalization of protein nitrogen appearance, history of parathyroidectomy, prescription of activated vitamin D, and self-reported compliance to phosphate binder.
*Data is presented as mean ± standard error, †data is presented as odds ratio (95% confidence interval). Bold values denote statistical significance at p-value < 0.05.
