It would be helpful to list the exact command you used and to
tell us the version # of meta you used (use -which meta- to get
the version #). Perhaps also, list your dataset and the results
obtained from meta.
The default output from meta from the version I have installed
does not automatically include the second table, so would not be
produced by the command you show. Furthermore, meta would not
accept se(ln_theta) as a legitimate variable name.
I suspect you are using the -ebayes- option or are actually
concerned about the CI being different (rather than
the HR point estimate being different). The point estimate is
simply read-in then directly printed for a default meta command.
If you used -ebayes-, the reported estimates can differ from the
raw estimates.
If it is the CI, then rounding may be involved or -meta- is
using an approach for generating CI's that is not the same as
the original paper used.
