Metformin Regulation of the Liver Circadian Clock and Metabolic Aging: A Systems Modeling Study.
Article in Metabolites, 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
introductionAging affects both metabolic and circadian systems, leading to disruptions in energy homeostasis and phase shifts in the circadian clock. Metformin, a widely used antihyperglycemic drug, exerts anti-aging effects by modulating key pathways in the liver and also influences the liver circadian clock. However, the optimal medication strategy, including dosage and timing, that achieves significant anti-aging effects while minimizing negative impacts on the circadian clock remains unclear. This study aims to identify a rational metformin administration strategy considering both aspects.
methodsAn extended mathematical model of the liver circadian clock incorporating metformin regulation was developed, and numerical simulations were performed to evaluate different dosing times and feeding conditions.
resultsMetformin administration at different times produced distinct effects on both the circadian clock and anti-aging outcomes. Administration during the increasing phase of CLOCK-BMAL1 concentration showed positive effects on the circadian clock and effective anti-aging properties. Regarding feeding patterns, a fed-like state was not conducive to anti-aging, whereas fasting was beneficial.
conclusionsThese findings highlight the importance of dosing time and feeding styles in optimizing metformin efficacy and provide insights into its potential pharmacological applications in anti-aging therapy.
