Linear regression models predicting end-of-treatment Diary Pain Intensity and KOOS Activity-Related Pain

DV = Average Daily Pain Intensity
Variable		Step R2	β	p
Step 1	Baseline Pain Intensity	.48** (for step)	.77**	.001
	Age		-.03
	Sex		.21
Step 2	Baseline CPM	.09* (for step)	-.30*	.03
DV = Koos Pain
	Variable	Step R2	β	p
Step 1	Baseline KOOS Pain	.30** (for step)	.47**	.02
	Age		-.05
	Sex		.16
Step 2	Baseline CPM	.13* (for step)	.37*	.03
