HAA ELISA and pIgA1 trap. a. HAA ELISA between healthy control and IgAN. There was significantly more HAA ELISA titer in the IgAN patients than in healthy controls (p < 0.05). b. pIgA1 trap between healthy control and IgAN. There was no significant difference of pIgA1 data (MFI) between IgAN patients and healthy controls. c,d. Correlation between pIgA1 trap and HAA ELISA. There was no inverse relation between pIgA1 trap data (MFI) and HAA ELISA titers in healthy controls (r² = 0.09, P = 0.11) (Figure 3c) and no direct relation in IgAN patients (r² = 0.005, P = 0.14) (Figure 3d). e. Correlation between Area-IgA and HAA ELISA. There was no significant correlation between Area-IgA and HAA ELISA titer (r² = 0.005, P = 0.69). f. Correlation between Area-IgA and pIgA1 trap. There was no inverse relation between Area-IgA and pIgA1 trap data (MFI) (r² = 0.03, P = 0.33).
