I am conducting an interaction analysis in PROC GLIMMIX and would like to present my interaction analysis with a single reference category. The interaction is between two categorical variables (2-level and 5-level variable). I have only been able to build obtain an output displaying ORs with separate reference groups. See tables below - I am attempting to display results similar to Table 6 with a single reference group.
proc glimmix data=cares2 method=quad;
class group outcome (ref="No") intervention(ref="No") area(ref="small") gender(ref="Female") /;
model outcome = intervention area gender age intervention*area / dist=binary link=logit ddfm=bw solution oddsratio;
random intercept / subject=group;
lsmeans intervention*area / slicediff=area adjust=bon oddsratio cl ilink;
run;
Thanks Reeza. I have attached an image of part of the Differences of intervention*area LSM output adjusted for multiple comparisons below.
Do the 'pre-underscored' variables (i.e. _intervention, _area) indicate the reference category that is being used to calculate the OR? In this case, would I be able to obtain these comparisons by locating the appropriate comparisons in this table, as opposed to creating a new variable?
