	R-value	P-value
Positive affect (PANAS)	0.078	0.673
Negative affect (PANAS)	0.248	0.171
Behavioral reward (BAS)	− 0.03	0.869
Behavioral drive (BAS)	− 0.017	0.929
Behavioral fun (BAS)	0.131	0.476
Behavioral inhibition (BIS)	0.128	0.484
Total mood disturbance (POMS)	0.071	0.7
Fatigue (PROMIS)	0.147	0.422
Trait anxiety (STAI)	0.486	0.005
State anxiety (STAI)	0.025	0.891
Depression (BDI)	0.172	0.354
Pain severity (BPI)	0.151	0.409
Pain interference (BPI)	0.108	0.557

Tested relationships between NAcc-MPFC circuit connectivity and cognitive, affective, and clinical measures within patients are shown. As described above, correlational analyses were Bonferroni corrected for a total of 6 independent comparisons and determined to be significant at the level of p < 0.008 (corrected threshold).
