This contrast will do it: [1 -1 0 0]
But I would first test [0 0 -1 1] to see if the slopes are different.
If not, then use [1 -1 0] with DOSS instead of DODS

I want to analyze the difference in cortical thickness between two groups (CU
and CI), adjusting for a covariate (cortisol
The model is actually, two independent linear models:
thicknessCU = CUOffset + CUcortisol*CUslope
thicknessCI = CIOffset + CIcortisol*CIslope
There will be four regression parameters:
