Correlation Coefficients for a Meta-analysis
Posted: Wed Jan 04, 2023 6:32 am
Hi,
I use the option of Correlation Coefficients for a Meta-analysis.
Unfortunately, I noticed that the z confidence intervals in the forest plot are a little different from what I get by manual calculation.
I use Model measures: Fisher's r-to-z option to get the z.
I was wondering is the formula that the software use different from the one I know.
The formula I use is:
[1/(n-3)]^0.5= SE
minZ = r-1.96SE
maxZ = r+1.96SE
Thank you
