Alcohol consumption: from biochemistry to behavior, health, and beyond.
Review in Frontiers in toxicology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Alcohol metabolism is a multi-step biochemical process driven primarily by hepatic oxidation of ethanol to acetaldehyde and then to acetate. Although this pathway protects the body from prolonged ethanol exposure, transient acetaldehyde accumulation generates substantial toxicity, and chronic alcohol intake activates auxiliary pathways that amplify oxidative stress, inflammation, and tissue injury. Both metabolic capacity and physiological response to alcohol vary widely between individuals, reflecting genetic and epigenetic variation in the alcohol- and aldehyde-dehydrogenase enzymes, the cytochrome P450 system, and modulating factors such as sex, age, body composition, nutrition, and overall health. In this review we consolidate 3 decades of biochemical, clinical, and epidemiological evidence into an integrated picture of alcohol's effects on the liver, brain, and other organ systems, with attention to oxidative stress, neurochemistry, glycoconjugate biology, and the convergence of alcohol- and metabolic-driven liver disease. We also examine recent advances in the treatment of alcohol use disorder (AUD) - including incretin-based pharmacotherapies, ketamine-assisted therapy, focused ultrasound neuromodulation, exercise interventions, and combination drug regimens - and we critically evaluate ongoing controversies surrounding moderate drinking, resveratrol, and the use of heterogeneous non-drinker comparison groups in observational studies. Finally, we discuss the changing social context of drinking, the role of endogenous ethanol/acetaldehyde systems in stress resilience across species, and the implications of these insights for personalized prevention and risk-reduction strategies. We conclude by proposing an exposure-susceptibility-context model that integrates the principal determinants of alcohol-related harm.
