Note. CKD = chronic kidney disease; TIA = transient ischemic attack; PCKD = polycystic kidney disease. Comorbidities/Charlson comorbidity scoring: (1 point) 1 = Myocardial infarction, 2 = congestive heart failure, 3 = peripheral vascular disease, 4 = cerebrovascular disease (includes TIA), 5 = dementia, 6 = chronic obstructive pulmonary disease, 7 = connective tissue disease, 8 = peptic ulcer disease, 9 = mild liver disease, 10 = diabetes without end organ damage (2 points), 11 = hemiplegia, 12 = moderate or severe renal disease, 13 = diabetes with end organ damage, 14 = tumor without metastasis (excluded if >5 years), 15 = leukemia, 16 = lymphoma (3 points), 17 = moderate or severe liver disease (6 points), 18 = metastatic liver disease, 19 = AIDS; cause of chronic renal disease: 1 = diabetes mellitus, 2 = ischemic nephropathy, 3 = glomerulonephritis, 4 = PCKD, 5 = obstruction, 6 = other.
