I have a problem when performing my meta-analysis:
Instead of Q-Statistic, I would like to use the option "BRESLOW' to
perform the Breslow-Day test for homogeneity of the odds ratio.
However, my "METAN" command is not working.
In my version of -metan- there is no breslow option, so the breslow
option not working would make sense. The version I got is pretty old so
it is possible that there is a version roaming around in an other
archive that -adoupdate- did not pick up. Which version of -metan- are
I typed -which metan- and got:
*! version 1.0 5May98 STB-44 sbe24
*! version 1.86 1Apr2004
However the command 27026 was trying is still not valid:
. metan a b c d, or breslow random
Breslow-Day heterogeneity option not available for D+L OR
The Breslow-Day test is in fact only available for fixed-effect
Mantel-Haenszel meta-analysis of odds ratios, i.e.
. metan a b c d, or breslow fixed
. metan a b c d, or breslow
- should work ("fixed" is a default). Note that the Breslow-Day test
statistic is still labelled "Heterogeneity chi-squared".
Hope that helps,
