It’s about Medical Project.
Our dependent variable which is preterm has 4 values/ groups (extreme preterm(Baby born <32 weeks of gestation ) Early preterm ( bon 32- 34 weeks of ga) late preterm( 35-36) and term (>=37 weeks of gestation)).
We are experienced in SAS in dealing with a binary (2 groups Preterm-YES & Preterm-NO) especially in our Proc-Genmod procedure to get our relative risks. Now we are stuck when we are trying subdivided preterm group/cohort( Extreme(<32) Early(32-34)Late(35-36)).
When we subdivided as above the SAS code/ Proc-Genmod code we already used for our binary outcome variable won’t work(which we know).
To resolve this troubleshoot we took an alternate/ shortcut path where we kept our outcome variable binary with meeting above subgroups by doing multiple models instead of single model (i.e., extreme Preterm vs Term- Model1; Early Preterm Vs Term - Model2; Late Preterm vs Term).
Our goal is to create a single model where our dependent variable has 4 values explained above my reference is term and I would like to get my RR(Relative Risk) for my 3 groups(extreme preterm, early preterm, Late preterm)
Need Suggestions,
Thanks
