^ap-Values were calculated by Fisher exact test for categorical variables and Wilcoxon two samples for continuous variables.

^bRelapse data excludes n = 20 who were not treated, n = 3 who were death, and n = 17 who did not have follow-up information on treatment response.

^cThe patients who only had renal relapse and achieved remission.
