Note: Values are mean ± standard deviation or percentages. Age, eGFR, albumin, body mass index, and hemoglobin were assessed at dialysis initiation; blood pressure was the average value for each patient over month 1; calcium x phosphorus and KT/V were the average value for each patient over months 4–6; cardiovascular risk factors or disease were assessed over the first 6 months.
CHF, congestive heart failure; CVD, cardiovascular disease; eGFR, estimated glomerular filtration rate; ESRD, end-stage renal disease.
