Tubulointerstitial Infiltration of M2 Macrophages in Henoch-Schönlein Purpura Nephritis Indicates the Presence of Glomerular Crescents and Bad Clinical Parameters

Figure 2

Area under curve (AUC) comparison of receiver operating characteristic (ROC) curves of tubulointerstitial M1 and M2 macrophages counts (a) and tubulointerstitial M2 counts and ISKDC classification (b) for the association with chronic renal failure. (a) AUC of tubulointerstitial M2 counts [0.872 (95% CI 0.745 to 0.950)] was wider than tubulointerstitial M1 counts [0.700 (95% CI 0.552 to 0.822)] (P=0.036). (b) AUC of tubulointerstitial M2 counts [0.866 (95% CI 0.736 to 0.947)] was wider than AUC of ISKDC [0.716 (95% CI 0.568 to 0.837)] (P=0.086). The AUC 95%, CI, and P-values in AUC comparison were obtained from DeLong method. ISKDC, International Study of Kidney Disease in Children.
