Erratum

This article [1] has been updated to include an R code and example dataset as Additional files 2 and 3. The R code and example dataset are also shown below.

In addition, the following text has been removed from page 4 of the article:

"To demonstrate the methods we used to fit the combined meta-regression, the online supplement includes example R code with an example dataset (example data are not real but are similar in magnitude and structure to the output from the case-crossover analyses in Stage 1".)

Finally, the following text is shown in the methods section:

To demonstrate the methods we used to fit the combined meta-regression, we have included an R code and example dataset as Additional files 2 and 3 (example data are not real but are similar in magnitude and structure to the output from the case-crossover analyses in Stage 1″.)
