Dear Michael, thank you for answering, this technique has been used for several years, and in general the original publications do not include the adjusted values. Imagine that it would be very difficult for all publications to include adjustment for the variables that interest us. Even some meta-analyzes adjust for years of publication, something interesting due to changes in the way patients are treated year after year.

Dear Martin
Unless either (a) the primary studies have published the adjusted OR, or
(b) you have the original data and can calculate it then I think the
answer is that waht you want to do is not possible.

That is, I need part of the crude OR, an adjusted OR for example, by age, cholesterol, sex, etc. Could I be oriented to achieve this type of adjustment in the meta analysis?
