Hi Stata users,
I'm trying to do a meta analysis of data from 10 different studies. The smoking variable in each study is stratified into categories (Category 1:1-10 cigarettes, Category 2: 10-20 cigs, Category3: 20-30 cigs etc.). I calculated the OR for each category (of smoking) by study. I then did a meta analysis and calculated the OR for each category by random effects model using the meta command:
meta or1 lcl1 ucl1, ci eform
meta or2 lcl2 ucl2, ci eform
I found that metap command can provide the p-value for each category (from p-values of each study for that specific category). Is there a way to get the p for trend BETWEEN the categories from the random effects estimate? I would like to report from the meta-analysis results if there is a dose-response relationship of smoking to the disease and if so what the p for trend is.
I will very much appreciate your help.
Thanks
Vijay
