Open circles are the data from the young subject population, closed gray circles from the elderly population. Blue data points are median values ± interquartile range (IQR) at a breath ethanol concentration of 0 g/l; red data points are median values ± IQR at a breath ethanol concentration of 0.5 g/l; green data points are median values ± IQR at a breath ethanol concentration of 1 g/l.
