Title: META with confidence intervals
I am combining two studies:
Study RR LCI UCI
Study 1 0.7 0.1 8.2
Study 2 0.6 0.1 6.4
With the command:
. meta rr ll ul, ci eform gr(f) print id(study)
However, the confidence intervals listed in the print are different from what I have entered:
Meta-analysis (exponential form)

Test for heterogeneity: Q= 0.010 on 1 degrees of freedom (p= 0.921)
Moment-based estimate of between studies variance = 0.000
