Autonomic Reactivity Tests of OCD Patients vs. Controls

	OCD		Control		P-Value	BH
	Median	Interquartile Range	Median	Interquartile Range
DBT-∆HR	27.50	16.84–31.00	21.21	17.42–28.50	0.39	0.071
E:I ratio	1.40	1.23–1.51	1.35	1.27–1.50	0.99	0.094
Valsalva ratio	1.75	1.46–2.00	1.70	1.41–2.05	0.89	0.091
LST-SBP	11.00	6.00–18.00	–4.00	–7.50 to 5.50	0.002	0.012a
30:15 ratio	1.50	1.36–1.59	1.48	1.34–1.68	>0.99	0.100
IGT	17.00	12.00–31.25	23.00	16.00–31.50	0.09	0.053
CPT	14.00	9.00–18.00	7.00	4.00–10.50	0.001	0.003a

BH, critical value for the Benjamini–Hochberg correction for multiple testing, (i/m)*Q, where i is the rank, m is the total number of tests (m = 34), and Q is the false discovery rate (Q = 0.10). DBT- ∆HR, change in heart rate during the deep breathing test; E:I ratio, ratio of heart rate during expiration and inspiration; LST-SBP, change in SBP during the lying to standing test; IGT, isometric grip test; CPT, cold pressor test.

Note: ^aResult was still significant after the BH correction (P < BH).
