Figure 2. Diamonds represent the extent of the confidence intervals. For group 1, test for heterogeneity, < 0.001; test for overall effect, < 0.001. For group 2, test for heterogeneity, > 0.2; test for overall effect, = 0.2. For both groups, test for heterogeneity, < 0.001; test for overall effect, < 0.001.
