A high fraction of the patients had PEth values above the suggested cutoff for heavy drinking and normal CDT values, verifying the superior sensitivity of PEth compared with CDT. The effect of age seems to be minor for both markers. Higher concentrations of CDT, but not PEth, were seen in males, indicating that PEth, as opposed to CDT, might be formed equally in men and women. Therefore, the bias due to sex is possibly present only for CDT, not for PEth.
