### Hoiw do I calculate weights for this graph?

Posted:

**Mon Dec 17, 2018 5:57 pm**Hello,

how do I calculate weights for this graph?

this is what I have:

ORg=0.9158 #odds ration for G study

Zg = 1.03944 # z score

SEg=log(ORg)/Zg #standard error

ORe=0.6304 #odds ration for E study

Ze=2.7876 # z score

SEe=log(ORe)/Ze #standard error

wg=1/(sqrt(SEg^2))

we=1/(sqrt(SEe^2))

I would like this graph to show me this Meta analysis as well, how do I enter that data?

Thanks
