EGF and renal fibrosis: While the urinary DKK-3 and PRO-C6 levels were highest in patients with more than 25% renal fibrosis (ci2+ci3, p-value for the comparison of ci0+ci1 vs. ci2+ci3 was 0.05 for urinary DKK3 and 0.01 for urinary PRO-C6), urinary EGF and C3M levels were highest in patients with less than 25% renal fibrosis (ci0+ci1) according to the Banff schema (p-value for the comparison of ci0+ci1 vs. ci2+ci3 was 0.025 for urinary EGF.
