Impact of Sex, Age, Body Composition and Kidney Function on the Relationship Between Self-Reported Alcohol Consumption and Phosphatidylethanol-Data From the HUNT Study.
Article in Basic & clinical pharmacology & toxicology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPhosphatidylethanol 16:0/18:1 (PEth) is a widely used alcohol marker, but how sex, body size and composition and kidney function affect the dose-response relationship between alcohol consumption and PEth is not fully understood.
objectiveThe aim of the study was to investigate whether sex, age, body size and composition and kidney function influence the estimate of alcohol consumed at a given PEth concentration.
methodsThis is a longitudinal population-based cohort study including 24 902 participants from the Trøndelag Health Study (HUNT4). Associations were assessed using a regression model.
findingsWhen analysed together, sex and soft lean mass were statistically significant independent predictors of alcohol consumption at a given PEth concentration. To achieve the same PEth concentration as a female, a male with identical body composition could on average consume 21% more alcohol, according to our model. Independent of sex, a person with 10% higher soft lean mass could consume 3.9% more alcohol to achieve the same PEth concentration. When soft lean mass was excluded, height and body weight became significant predictors.
conclusionsSex, body composition and body size may have an impact on the dose-response relationship between alcohol consumption and PEth concentration. Thus, these factors will contribute to the uncertainty when estimating ethanol intake from a given PEth concentration.
