HD, hemodialysis; PD, peritoneal dialysis; mo, months.

Data are means (± SD), median (95% Confidence Intervals) and [range].

*P values determined according to t-test for normally distributed continuous variables, Mann-Whitney rank-sum tests for non-normally distributed continuous variables.

^†Weight measured after hemodialysis.
