1 Among current smokers only; * Denotes significant (at p < 0.05) overall difference between countries for that characteristic. Superscript letters beside values denote significant differences between countries (i.e., different letters indicate a significant difference between countries for that characteristic). For example, the mean age of the adult sample in Bangladesh (denoted “a”) differs from China (denoted “b”) but not India (also denoted “a”).
