Data are presented as the medians (25th and 75th percentiles), the mean ± SD. n* is the available n for a given value. Where not specified, the available n is the same as the total number of cases in the top row
BN, benign nephrosclerosis; MN, malignant nephrosclerosis; TAIF, tubular atrophy/interstitial fibrosis
