From: Role of serum complement C3 and C4 on kidney outcomes in IgA nephropathy
Incidence of outcome expressed as incidence rate ratio (100 patients[pts]/year) stratified by baseline C3. Low group had a higher incidence, 16.3 events (95% CI 7.3–36.3) compared with Medium (2.9 events 95% CI 1.4–6.1) and High group (1.7 events 95% CI 0.2–11.8).
