The authors have identified an error in the above article. The largest and most powerful study that has been done to date1 was omitted in Tables 1 and 2. Correa et al1 was published after the original submission and before the acceptance of a revised version of the above article, and was unfortunately not included in the final article. The data in the study were important for the meta-analysis, and the inclusion of Correa et al's results does not alter the conclusions of the paper, but makes them stronger. The authors regret this error.
