Hierarchical regression models predicting inflammation (CRP) built from PHQ-9 and SBI-R

	B	t	P
Model One
Step 1:
Sickness Behavior (SBI-R)	0.45 (0.01)	4.62	<0.001
	F = 21.38, Adjusted	R² = 0.19
Step 2:
Sickness Behavior (SBI-R)	0.51 (0.01)	3.143	0.002
Depression (PHQ-9)	−0.08 (0.02)	−0.477	0.64
	F =10.71, Adjusted	R² = 0.18
Model Two
Step 1:
Depression (PHQ-9)	0.33 (0.01)	3.23	0.002
	F =10.45, Adjusted	R² = 0.10
Step 2:
Depression (PHQ-9)	−0.08 (0.02)	−0.48	0.64
Sickness Behavior (SBI-R)	0.51 (0.01)	3.14	0.002
	F =10.71, Adjusted	R² = 0.18
