Analysis of the first breath sample (n=88) illustrating the difference between the BAC and the BrAC with a Bland-Altman plot. (a) A mean bias of 0.31 mg/g was found between the BAC and the BrACmeas, upper limits of agreement (LOA) of 1.09 mg/g and lower LOA of -0.46 mg/g. (b) No bias was found between the BAC and the BrACest, upper LOA of 0.68 mg/g and lower LOA of -0.70 mg/g.
