*, ** and *** indicate significance at 10%, 5% and 1% levels, respectively. SEs are in parentheses. The estimation controlled for individual sociodemographic and economic characteristics, different tobacco-related warnings, advertising, promotional initiatives, and perceptions related to smoking and tobacco taxes. The corresponding marginal effects are provided in online supplemental table 1. For the link test, the insignificance of coefficients of the square of the predicted values indicates the parsimonious nature of the specifications.
