I'm performing a single group meta-analysis with continuous data. Data are from different follow-up points as efficacy evaluation of a single surgical intervention. How big is the risk for regression to the mean creating effect?
Dear Stefano,
Could you clarify your question ? What risk are you talking about ?
By single group meta-analysis, do you mean that all the data is from a single study ? Or do you mean that you are not using any moderator ?
Dear Emilie,
thank you very much for your prompt response.
Data derived from the control groups of different studies, you can take a look at the file I'm attaching you to better understend the disegn of the meta-analysis. You can look here for the risk to the mean definition http://en.wikipedia.org/wiki/Regression_toward_the_mean .
Best Regards
I think your question is above my statistical knowledge. If you don't have an answer here, I suggest you ask it on the cross-validated website, dedicated to answering statistical question.
