Participant Flow

Consecutive patients with biopsy-proven ACR were recruited in the kidney transplant Clinic at UCSF and were randomized to either the Rituximab or the control group.

18 patients were consented to participate. 3 patients failed eligibility screening prior to treatment assignment. 15 were eligible, 10 were in the Rituximab group and 5 in the no-Rituximab group.
