Clinical baseline characteristics of the patients at the time of inclusion in the study.

At the time of inclusion in the study 16 (48%) patients had detectable PLA2R-Ab in the serum. Proteinuria at inclusion in the study was higher in PLA2R-Ab positive patients compared to PLA2R-Ab negative patients but this difference did not reach statistical significance. Serum creatinine and age were not different between PLA2R-Ab positive and PLA2R-Ab negative patients. Significantly more PLA2R-Ab positive patients received immunosuppressive treatment during the follow-up time.Clinical baseline characteristics of the patients at the time of inclusion in the study.
