aAuctions conducted from November 2010–November 2011
bThe only demographic characteristics that differed across treatment groups at a significance level of 0.05 or less was the over 50 age group (p < 0.01). No other differences in demographic characteristics were found to be significant at the 5 % level using a chi-squared test
cThe only demographic or background characteristics where there were statistically significant differences in the percentage who tried ST products was for females (p < 0.05) and for those who had used smokeless tobacco at some point in the past (p < 0.01)
