Figure 2. Funnel plot of the point estimates of the effect of recombinant bovine somatotropin (rBST) on 3.5% fat corrected milk (FCM) versus the standard errors of those estimates. Evidence of publication bias would be the presence of numerous points in the upper right quadrant (large effect, large standard error) with few being present in the lower right quadrant (small or negative effect, large standard error).
