  1. Median and interquartile (IQ) range of blood alcohol concentration (BAC) levels are presented. Differences in BAC levels across the categories of gender, age, occupational activity, ticket type, status of entering/exiting, day of measurement and entrance were measured using the Mann-Whitney U-test or the Kruskal-Wallis test. Data is missing for the following variables and number of participants: BAC levels (n = 2), gender (n = 18), age (n = 4), occupation (n = 8), ticket type (n = 8) and entering/exiting (n = 16)
