Mean age (52 years vs. 54 years)b    0.16
Surgery – Evaluation. interval (34 vs. 36 months)b    0.41

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
Axilla status (positive vs. negative) 1.3 0.7-2.6 0.37

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