	NEO-FFI Neuroticism
	Model 1		Model 2		Model 3
Variable	B	95%CI	B	95%CI	B	95%CI

Olfactory detection	0.17	[−0.57–0.91]	0.23	[−0.48, 0.94]	0.112	[−0.602, 0.826]
Trigeminal chemosensory detection			−0.20*	[−0.40, 0.003]	−0.20*	[−0.40, −0.003]
Trigeminal chemosensory pain			−0.05	[−0.17, −0.04]	−0.06	[−0.13, 0.09]
Electrical cutaneous detection					−6.65	[−14.8, 1.52]
Electrical cutaneous pain					−0.18	[−0.54, 0.17]
R2	0.00		0.09		0.13
F	0.21		3.37*		2.82*
ΔR2			0.09		0.03
ΔF			4.94		1.91

Only the inclusion of the variables olfactory detection, trigeminal chemosensory and electrical cutaneous detection and pain led to significant regression models and thus only those models are shown.

Note. N = 103. CI = confidence interval.
