Association of Serologic Status as a Predictor of Pain Severity or Neuropathic Pain Adjusted for Age, Sleep Quality and Psychological Distress.^*

	Pain Severity Outcome		Neuropathic Pain Outcome
Adjustor	Effect Estimate (95% Confidence Interval)	p-value	Odds Ratio (95% Confidence Interval)	p-value
Seropositive vs. Seronegative	−1.17 (−1.88, −0.47)	0.001	0.81 (0.32, 2.01)	0.642
Age (per decade)	0.17 (−0.13, 0.48)	0.264	0.98 (0.65, 1.49)	0.937
Sleep Quality	0.12 (0.04, 0.20)	0.005	1.05 (0.94, 1.17)	0.354
Psychological Distress†	0.12 (0.07, 0.17)	< 0.001	1.12 (1.04, 1.21)	0.003

^*Estimates for “Pain Severity” outcome denote expected Pain Severity level per change in covariate, holding constant all others. Odds ratios for “Neuropathic Pain” outcome denote multiplicative odds of Neuropathic Pain vs. Non neuropathic pain for participants per unit difference in the covariate, holding constant all others.

^†Psychological Distress variable = HADS composite score
