aData shown are for the entire casino, i.e., for the total smoking and nonsmoking areas. All occupancy rates and active-smoker proportions areas are expressed as a percentage (% Occupancy;% Active Smokers). Occupancy is the number of total patrons divided by the theoretical capacity of all smoking areas. Smoker-activity as a function of occupancy for main smoking areas is presented in Figure  2. Occupancy for nonsmoking areas (slots + tables) relative to main smoking areas is presented in Figure  3.

bDuring the second visit to Casino F, patron occupancy was substantially higher than the first visit, resulting in a decrease in active smoker count proportion. We considered this event to cause unlikely deviations and therefore excluded it from our overall analysis. It is, however, presented here in disaggregated format for reference. The overall row contains the row-wise sums for the Patrons and Smokers columns, and the overall percentages across all casinos for a given visit or across all visits. Data for the overall row excludes all the results from the second visit to Casino F (numbers in bold).

cThe overall mean difference in the last column excludes the second visit to Casino F (number in bold), and considers only the magnitude of difference between visits, not the direction.
