![ROC curve for three biomarkers—IgA1, Gd-IgA1 and IgA-α1-microglobulin complex—for the diagnosis of IgAN. (A) For the diagnosis of IgAN, the AUC for the IgA-α1-microglobulin complex was significantly higher than that for IgA1 {0.862 [95% confidence interval (CI) 0.807–0.917] versus 0.732 [95% CI 0.652–0.811]; P < 0.001}. (B) In addition, the AUC for the IgA-α1-microglobulin complex showed a higher tendency than that for Gd-IgA1, although statistical significance was not reached [0.862 (95% CI 0.807–0.917) versus 0.803 (95% CI 0.739–0.867); P = 0.076].](https://oup.silverchair-cdn.com/oup/backfile/Content_public/Journal/ndt/36/5/10.1093_ndt_gfaa352/1/gfaa352f5.jpeg?Expires=1750583916&Signature=c9S7gXAIu6q7a2L0VleXGs3yvOgyKkEmf0k267ohUuK6~ySp30Yhar6hORI0OzHtVR2YpMvrinxyf-Fa23Zc01i0yHv-DMb8FGj4fQUHIzpGLCRwDwj0HHEYvFYAXmGkQ6sL8yJmTlyu84OFcIvY0ymjRtjlTH6r0HRv4hiocMayBJsBHjtNAg0DEK~-nzsIYf9u1cBef609WZRPzGsmBT7lb5OWMOcBDxGi69g~YV9daTtiJjEu9kW403mO6~Owj7qdBrzR0CPwxoI40-QfGjcZU2RNhmYAwngiaqH7EfydrEg5jnI-9Iexx0yRLnWMnR1EZy2ScNlUFMP46bD8Qw__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
