I'm trying to determine how each of my IV variables (sex, agegroup, gmfcs, deprivation and epilepsy) explain a participant's totalR score (DV). So, I was advised to "control" each of them to assess their individual impact. Might the below approach be ok for this please?
regress totalR i.sex, robust
regress totalR i.sex, i.AGEgroup, robust
regress totalR i.sex i.AGEgroup i.gmfcs_cat, robust
regress totalR i.sex i.AGEgroup i.gmfcs_cat i.deprivation_cat, robust
regress totalR i.sex i.AGEgroup i.gmfcs_cat i.deprivation_cat i.Epilepsy, robust

Many thanks for your guidance and apologies if this is a basic question.
