Fig. 2From: Does wine glass size influence sales for on-site consumption? A multiple treatment reversal designPercentage change in daily ml of wine sold, compared to sales with the standard glass (error bars show 95 % CIs). All regressions controlled for day of the week, overall sales (excluding wine sales) in the establishment each day and maximum daily temperature in Cambridge. Standard glasses were the reference group for glass size. Coefficients and CIs were back-transformed (using 100*[exp(B)-1]), to reflect percentage change in daily ml of wine sold when using different glass sizes compared to the standard glassBack to article page
