Analyses were conducted on past‐year smokers who reported having visited their general practitioner (GP) in the last 12 months and who had complete data on all covariates. Each form of advice or support was modelled separately. Statistically significant (P < 0.05) associations are shown in bold type.
Occupational social grades ABC1 represent more advantaged groups; C2DE more disadvantaged groups.
BF = Bayes factor; CI = confidence interval; H0 = null hypothesis (i.e. advice/support not associated with increased odds of quit attempt); H1 = experimental hypothesis (i.e. advice/support associated with increased odds of quit attempt); OR = odds ratio; SSS = stop smoking services.
Includes suggestions that the patient use an e‐cigarette, go to a specialist stop smoking adviser or group or see a nurse in the practice; offer of prescription medication; or advice to stop smoking without offer of support.
