Pearson’s correlation analyses between significant reduced GMV in PD patients compared to HC subjects identified in the ROI analysis with clinical scores

	SIGH-A (p)	PAS (p)
Amygdala R (non-smoker)	−0.173 (0.040)*	−0.076 (0.295)
Amygdala R (whole group)	−0.098 (0.107)	−0.076 (0.295)

Notes: GMV, gray matter volumes; PD, panic disorder; HC, healthy control; ROI, region of interest; SIGH-A, Hamilton Anxiety Scale; PAS, Panic and Agoraphobia Scale; R, right.

Missing values in HC subjects: SIGH-A: 48; PAS: 31.
