Comparison of self-estimation accuracy between the two intervention days. To evaluate the accuracy of drinkers’ self-estimation, the volunteers were asked to report when they perceived to have reached the legal driving limit of 0.05% BrAC. Data show the difference between measured BrAC and self-estimated BrAC. The p value was calculated using a paired t test. Summary statistics: Study day 1: − 0.036/ − 0.017/ − 0.007/ 0.004/ 0.032 (Min/ Q1/ Median/ Q2/ Max); study day 2 = − 0.032/ − 0.007/ 0.000/ 0.006/ 0.039 (Min/ Q1/ Median/ Q2/ Max).
