Boxplots of hosphatidylethanol (PEth) concentrations by: a Alcohol Use Disorders Identification Test (AUDIT) score (n = 60, b average daily alcohol consumption the last week prior to hospitalization (n = 60) and c) diagnosed with alcohol disorder (n = 177). Two male patients in figure a) and b) with PEth concentrations above 1.5 μmol/L are not shown to increase readability. One of these had a PEth concentration of 2.00 μmol/L, no alcohol diagnosis, an AUDIT score of 11 and reported drinking 1-3 alcohol units per day. The other had a PEth concentration of 3.03 μmol/L, an alcohol diagnosis, an AUDIT score of 14 and reported drinking ≥4 alcohol units per day. In figure c) six patients with PEth concentrations above 1.5 μmol/L are not shown. Boxes represent the first quartile and third quartile, the central line represents median, whiskers represent minimum and maximum levels excluding outliers. Circles represent outliers with values between 1.5 and 3 times the interquartile range, the asterisks represent outliers more than 3 times the interquartile range
