a	Single-task emotion perception	B	Wald Z	p	OR	95% CI
	SFMPQ pain	0.070	3.75	< 0.001	1.077	[1.168 2.139]
	DASS depression	− 0.312	− 2.59	0.010	0.732	[0.004 0.723]
	DASS anxiety	0.435	2.85	0.004	1.545	[0.565 0.910]
	Response time	0.001	0.67	0.503	1.001	[0.998 1.005]
b	Dual-task emotion perception	B	Wald Z	p	OR	95% CI
	SFMPQ Pain	0.069	6.14	< 0.001	1.072	[1.050 1.097]
	DASS Depression	− 0.293	− 4.29	< 0.001	0.746	[0.647 0.847]
	DASS Anxiety	0.428	5.14	< 0.001	1.533	[1.312 1.819]
	Response Time	0.001	2.35	0.019	1.001	[1.000* 1.002]

B parameters reflect the log odds of being a CMI patient for a one unit increase in the predictor variable. For future comparison, the Akaike Information Criterion (AIC) for the two models were as followed – single task = 103.45; dual-task = 286.11
