In Reply: We agree with Dr Bassler and colleagues
that the exclusion of non–English-language studies may lead to bias
in meta-analysis results. Our MEDLINE search included all languages and revealed
25 publications of potential interest that were not in English. However, we
felt that excluding these publications would not lead to significant bias
in our meta-analysis. Of the 15 non-English studies that we were able to retrieve,
none met our inclusion criteria. The remaining studies were either published
prior to 1985, the earliest date that an English-language study was identified
as meeting our inclusion criteria, or had an English abstract available online
indicating that the study was a case series and therefore could not provide
relative risks (RRs).
