  1. aAdjusted on age and education
  2. bRelative index of inequality
  3. Example: the adjusted odds ratio for smoking in the group of Maghrebin men is 1.23. In this group of men, the educational gradient is reflected by a RII of 3.0. Among Maghrebins, the male-to-female odds ratio is 5.48. This ratio is 4.14 times higher than that of the reference group, which is 1.33
