Renal survival. (A) Kaplan-Meier renal survival analysis comparing MIg-C3G patients who received chemotherapy, immunosuppressive therapy, or conservative therapy. (B) Kaplan-Meier renal survival analysis comparing MIg-C3G patients who achieved or did not achieve hematological response. (C) Kaplan-Meier renal survival analysis comparing MIg-C3G patients with or without hematological response (complete response or very good partial response) in 37 patients who received treatment (immunosuppressive therapy or chemotherapy). Data regarding the hematological response were available in 36 of the 37 patients. CR, complete hematological response; HR, hematological response; IS, immunosuppressive; VGPR, very good partial response.
