Initiation ratio
Trends * education level 0.94 (0.87 to 1.02) 0.86 (0.79 to 0.92)
Trends * income level 0.92 (0.84 to 1.01) 0.97 (0.90 to 1.06)
Quit ratio

† Odds Ratios and 95% confidence intervals are given for smoking prevalence, initiation ratio, and quit ratio, Bètas and 95% confidence intervals are given for smoking consumption. All regression coefficients were adjusted for age group. Regression coefficients in italics were non-significant.

* Education level and income level were entered as independent variables in separate analyses.
