ACE, angiotensin-converting enzyme; CI, confidence interval; GIN, granulomatous interstitial nephritis; IFTA, interstitial fibrosis and tubular atrophy; OR, odds ratio; PTH, parathyroid hormone; sCr, serum creatinine.

^aOdds ratio with 95% confidence interval and P values were calculated using logistic regression model.

^bOdds ratio is per unit change in regression.

^cP < 0.05.
