Bold values indicate significance (p<0.05). Stata ‘margins’ were used to estimate the predicted values and ‘contrasts’ were used to test for differences in predicted values.
Models controlled for the US$2 increase in the California cigarette excise tax (April 2017) and for seasonality in all models except ENDS.
*Full regression results for each of these outcomes and study cities are available in online supplemental table 2.
ENDS, electronic nicotine delivery systems; SLT, smokeless tobacco.
