*Data are presented as mean (SD) or median (range) if not stated otherwise.
†Number of cases with missing values for patients on HD: 2 for CRP, 4 for cholesterol, 2 for TIBC, otherwise the dataset was complete. Number of cases with missing values for control subjects: 34 for albumin, 34 for creatinine, 31 for hemoglobin, otherwise the dataset was complete.
