  1. Note: * The aORs in models 2 to 5 are adjusted for the demographic and key socio-demographic variables (ie, deprivation), models 3 & 4 for smoking knowledge (of harm) and behaviour variables, model 4 for smoking beliefs and attitudes, and model 5 is the same as model 2 but with each other knowledge, behaviour or belief variable included just on its own (and not adjusted for other such variables). The included variables from the univariate analyses that became not significant in the models (at p < 0.05) were subsequently omitted from the final respective models, except for those considered critical to our conceptual framework (see Methods).
