Prognostic Factors for Survival and Relapse in ANCA-Associated Vasculitis with Renal Involvement: A Clinical Long-Term Follow-Up Study

Figure 3

(a) Median GFR during follow-up in diagnostic groups GPA and MPA. For up to 5 years, the difference between the diagnostic groups was significant (p<0.02, Mann–Whitney U test). (b) Median GFR during follow-up in renal histology categories. For up to 5 years, the difference between histology categories was significant (p≤0.001, Kruskal–Wallis test), and the Bonferroni-corrected pairwise comparisons detected a significant difference between the focal and sclerotic AAGN (p<0.001). The error bars indicate the interquartile range.
