Phosphatidylethanol in Comparison to Self‐Reported Alcohol Consumption Among HIV‐Infected Women in a Randomized Controlled Trial of Naltrexone for Reducing Hazardous Drinking

Abstract

The magnitude of the correlation between PEth and self-reported alcohol consumption was small. Caution is needed when using either self-report or PEth as a sole outcome measure for alcohol behavior changes in clinical trials.
