Note: CI, confidence interval. Percent change intensity was estimated by PROC SURVEYREG procedure using the log of number of daily smoking as an outcome. Beta coefficients were multiplied by 100. Negative sign means percentage reduction in daily smoking. Estimates were also adjusted for WHO world region of the survey country, compliance with smokefree policy in the country, and age- and sex-adjusted adult smoke prevalence in the country.
