[R-meta] doubt about meta analysis
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.

I am wanting to do a meta analysis with the meta and metafor packages in R. I have not managed to adjust the odds ratio for certain covariates. 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? > From already thank you very much > > Lorenzo Mart?n Lobo MTSAC, FACC, FESC > Especialista Jerarquizado en Cardiolog?a > Ex Jefe de Unidad Coronaria > Hospital Militar Campo de Mayo > Miembro Titular de la Sociedad Argentina de Cardiolog?a > Fellow American College of Cardiology > Fellow European Society of Cardiology > Miembro del Area de Investigaci?n de la SAC > Director del Consejo de Aterosclerosis y Trombosis de la SAC > Ex Director y actual Miembro Asesor del Consejo de Epidemiolog?a y Prevenci?n Cardiovascular de la SAC > > Instructor de ACLS de la AHA para la Fundaci?n Cardiol?gica Argentina > > > [[alternative HTML version deleted]] > > > _______________________________________________ > R-sig-meta-analysis mailing list > R-sig-meta-analysis at r-project.org > https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fstat.ethz.ch%2Fmailman%2Flistinfo%2Fr-sig-meta-analysis&data=02%7C01%7C%7Cfcc91662996d4ce06d8c08d6aaf37e10%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636884360093826007&sdata=88yG64jwoEO3sH3lzRIySoq1FtKpeFO85IMVrBbisyk%3D&reserved=0 > -- Michael https://eur02.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.dewey.myzen.co.uk%2Fhome.html&data=02%7C01%7C%7Cfcc91662996d4ce06d8c08d6aaf37e10%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636884360093836012&sdata=SFA%2BMQszUs9F0mMQ9IyA%2BlK2pf0UaV2ajmmxQ9a%2BQMs%3D&reserved=0
