Data are represented as mean ± standard deviation

∆sales is the percent increase in sales on one day in 2007 as compared with the sales on the same date in 2006; adjusted values of sales in 2007 are ∆sales adjusted for relative changes in the number of total monthly visitors in August to November of 2007 from the year-earlier months; P for the trend was tested by Spearman’s rank correlation coefficient (ρ)
