Figure 2.

Effect of steroids on composite renal endpoint (ESRD or doubling of serum creatinine or halving of GFR) in patients with IgA nephropathy. Boxes and horizontal lines represent relative risk and 95% CI, respectively, for each trial. Size of boxes is proportional to weight of that trial result. Diamonds represent the 95% CI for pooled estimates of effect and are centered on pooled relative risk. Dotted lines on the center of the diamonds represent pooled relative risk. Solid lines represent that the relative risk is 1.
