rank test or McNemar’s χ2 test for bivariate analysis and non-paired differences using Wilcoxon rank sum test.
Analyses of changes within pairs were restricted to participants who responded to baseline and follow-up surveys,
remained employed in a bar and didn’t change their smoking status.
Participants 329 bar workers recruited at baseline (288 ROI and 41 in NI). Total ineligible: 48 (40 were no longer in the bar
trade, 7 moved, 1 died). Lost to follow up: 23 uncontactable; 9 refused.
Follow-up rate 89% (220/248) of those eligible or 76% overall in Rep of Ireland
Follow-up rate 88% (29/33) of those eligible or 71% in NI
Analysis restricted 158 (138 ROI and 20 in NI) who were nonsmokers at baseline and follow up
