Values for continuous variables are given as median (25th–75th percentile) or mean±SD. IDH, intradialytic hypotension; PTH, parathyroid hormone; Hb, hemoglobin; hsCRP, high-sensitivity C-reactive protein; spKt/V, single pool Kt/V; BNP, B-type natriuretic peptide.
a
Baseline refers to the average values over the first 2 weeks of the study.
