  1. a The difference between rates of men according to revascularization is statistically significant (p = 0.0003)
  2. b The differences between means (age and Comorbidity index) according to revascularization and number of drug classes are all statistically significant (p < .0001)
  3. c The difference between rates of men according to number of drug classes is not statistically significant (p = 0.3889)
