There's no problem in using continuous exposures in meta.summaries() in the rmeta package. For each study, compute your log odds ratio and its standard error, and feed them in. You just need to make sure that the odds ratio is in the same units in each study, of course. -thomas -- Thomas Lumley Professor of Biostatistics University of Auckland ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
