  • Bolded results are statistically significant (at the p < 0.05 level).

  • * The adjusted ORs (aORs) represent those odds for agreement with the statement in the title about banning cigarette sales (as in the title of the table) compared with those not agreeing. The aORs in models 1, 2 and 3 are adjusted for the demographic and key socio-demographic variables (eg, deprivation) and model 3 for mental health, heaviness of smoking and various other smoking-related beliefs and behaviours (see the Methods section).

  • Not adjusted for complex sample design.

  • See the Methods section and an online Methods Report 26 for further details on these measures.
