Dear colleagues, Good morning. I would like to ask about multivariate regression analysis.
I researched the OR between risk factors and outcome diseases.
In the a univariate logistic regression analysis, I got such risk factors which would be able to into the multivariable

logistic disease ib1.gender // reference group is male
logistic disease ib2.dry_skin// reference group is no
logistic disease ib2.wheezing_noise// reference group is no
logistic disease ib2.sever_symdrome// reference group is no I found those four groups P<0.2, so I would like to run multivariate analysis, however, the groups (e.g. dry_skin, wheezing_noise, sever_symdrome) have 0.5-1% missing data.

Therefore in the multivariate regression analysis,
Is it possible to run

logistic disease ib1.gender ib2.dry_skin ib2.wheezing_noise ib2.sever_symdrome

Looking forward to hearing from you.
Thank you very much.
