Samples originated from individuals in North Rhine-Westphalia, including mainly driving under influence (DUI), but also other alcohol-related offenses. BAC was measured via gas chromatography with a flame ionization detector and an enzymatic (ADH) method.

The study population was predominantly male (77%), with a mean age of 37 years. Most cases involved traffic offenders resp. drivers of motor vehicles, primarily cars. BACs were \u2265\u20091.1\u00a0g\/kg in 73.5% and \u2265\u20091.6\u00a0g\/kg in 47.1% of cases. EtG concentrations ranged from below cutoff to 8,627 ng\/mL (median: 2,957 ng\/mL), and PEth ranged from below the lower limit of quantification (LLOQ) to 1,520 ng\/mL (median: 140 ng\/mL). A moderate correlation was found between BAC and PEth (\n                      <jats:italic>r<\/jats:italic>\n                      \u2009=\u20090.48,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.01), and a strong correlation between BAC and EtG (\n                      <jats:italic>r<\/jats:italic>\n                      \u2009=\u20090.79,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
