Kaplan-Meier curves demonstrating renal survival in a 5 tier measure of interstitial inflammation* by total conventional light microscopy (TLM) using hematoxylin and eosin and periodic acid---Schiff stains without subtracting areas with interstitial fibrosis and tubular atrophy. The number of patients available for analysis in each grade is provided. P values were derived using a log rank trend test. *5 tier measure: none/grade 0=0%; minimal/grade 1= <10%, mild/grade 2= 10–25%, moderate/grade 3=26–50%; or severe/grade 4= >50%.
