Variables	Odds ratio	95% CI	P- value^a
Mean age (52 years vs. 54 years)^b			0.16
Surgery – Evaluation. interval (34 vs. 36 months)^b			0.41
Surgery (mastectomyvs. conservative breast surgery)	1.4	0.6-3.5	0.38
Incision (single vs. separate)	0.9	0.4-2.0	0.95
Surgery (dominant arm vs. non-dominant arm.)	1.9	1.0-3.7	0.04

^aMultivariate analysis: multiple logistic regression tests for binary variables and multiple linear regression for continuous variables.
^bMultiple linear regression for continuous variables does not generate odds ratio and CI.
CI: confidence interval.
