Abbreviations: = Number of observations; OR = Odds ratio; C.I. = Confidence interval; IPTH = Intact parathyroid hormone; ACEI = Angiotensin converting enzyme inhibitor; ARB = Angiotensin receptor blocker; AVF = Arteriovenous fistula. Factor of hypertension was dropped out from analysis because of zero events in repeated arteriovenous fistula failure among patients without hypertension; .
