Example in my case: Using a mixed model for getting the rates of "failure" in patients undergoing surgery. Need to use mixed model because patients can have one to two eyes undergoing either of two treatment (surgeries) types.   Example of how data is structured: PtID    Eye    Treatment    Failure 1       0           Surgery1           0 1       1            Surgery1           0 2       0          Surgery2           1 3        1           Surgery1            0 How I built my model so far: proc glimmix data=mydata method=laplace; class PtID Treatment Eye; model failure = Treatment|Eye; random Eye / subject=PtID(Treatment) type=cs; lsmeans Treatment / cl oddsratio ilink; title 'Eye Surgery'; run;   I really want to find the 95% odds ratio of failure between the two treatments. Could you please let me know what code I'll need? Am I way off in terms of how I'm organizing my data or how I've built my model? Thanks in advance   ... View more

Hi. Very new to SAS. I'm trying to make a Recovery over time curve if that's a thing or a KM curve where it starts at or near 0 and goes towards 1 as my subjects recover. I want to plot two lines on it using the strata variable Treatment, too. Is there a way to do this? In my mind, the data might look like: Time (Months), Recovery(0=censor, 1=recovered), and Treatment (0, or 1). Please let me know if I'm completely off! I'm so lost. Thank you in advance for your help! ... View more
