Logistic Regression Model for Presence of Chronic Pain Following Breast Cancer Surgery (n = 93)

Risk Factor Variable	Coefficient	Standard Error	P	Odds Ratio*	95% Confidence Interval
Age (yrs)	−0.05	.02	.04	0.95	0.91–0.99
Breast cancer history	−0.66	.56	.24	0.52	0.17–1.55
Preoperative breast pain	−0.17	.56	.76	0.84	0.28–2.54
Surgery type	1.03	.60	.09	2.81	0.87–9.14
Cancer status	0.00	.65	.99	1.00	0.28–3.54
Radiation therapy	0.94	.57	.10	2.56	0.84–7.76
Marital status	0.67	.54	.21	1.95	0.68–5.55
Clinically meaningful acute pain	0.85	.52	.10	2.33	0.85–7.76

NOTE. No emotional functioning variables contributed significantly to the model when considered for stepwise entry.

^*Odds ratios are adjusted for other terms included in the model; for continuous variables, these ratios reflect the multiplicative increase in odds for chronic pain for every 1-point change in the variable.
