In Reply: Dr McGuire and colleagues are correct that the Edmonds et al1 meta-analysis SMD result presented in Figure 4 of our article is erroneous and should have been “−0.77 (95% CI, −1.26 to −0.28).” The incorrect value in the figure was the one that appeared in Figure 1 in the version of their Cochrane review that was current the summer of 2005, which we used in our study.
