Background and Aims Quantifying alcohol intake is crucial for subclassifying participants with steatotic liver disease (SLD) and interpreting clinical trials of alcohol-related liver disease (ALD) and metabolic dysfunction and alcohol-related SLD (MetALD). However, the accuracy of self-reported alcohol intake is considered imprecise. We compared the diagnostic and prognostic utility of self-reported alcohol intake with blood-based biomarkers of alcohol intake: phosphatidylethanol (PEth) and carbohydrate-deficient transferrin (CDT). Methods We studied 192 participants from two randomized controlled trials on MetALD and ALD, all with current or former excessive alcohol intake (≥24/36 (♀/♂) grams daily for at least one year) and biopsy-proven liver disease. We assessed self-reported alcohol intake, PEth and CDT at four time points. We collected follow-up data on hepatic decompensation and death manually through electronic medical records. Results Most participants were male (n=161, 84%) with a mean age of 59 (SD 9) years and 73 participants reported one-week abstinence before inclusion; the remaining reported a median alcohol intake of 43 g/day. Median PEth was 0.5 μmol/L (IQR: 0.0-1.3) and %CDT=1.9 (IQR: 1.6-2.3). Of 32 patients reporting at least six months of abstinence; 27 (84%) was confirmed by PEth<0.05 μmol/L. Self-reported alcohol intake correlated well with PEth (r=0.617) and moderately with CDT (r=0.316). Self-reported alcohol intake, PEth and CDT all predicted hepatic...
