1 · What the graph read from it

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.

2 · The registry

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

The orchestration of cellular metabolism requires the integration of signals related to energy stores and nutrient availability through multiple overlapping mechanisms. AMP-activated protein kinase (AMPK) is a pivotal energy sensor that responds to reductions in adenylate charge; however, studies over the past decade have also positioned AMPK as a key integrator of nutrient-derived signals that coordinate metabolic function. This Review highlights recent advances in our understanding of how AMPK senses nutrients and regulates metabolic activity across tissues, timescales and cell types. These effects are mediated through the phosphorylation of substrates involved in metabolite trafficking, mitochondrial function, autophagy, transcription, ubiquitination, proliferation and cell survival pathways, including ferroptosis. Particular attention is given to the role of AMPK in the pathophysiology of obesity, type 2 diabetes, metabolic dysfunction-associated steatotic liver disease, cardiovascular and renal diseases, neurodegenerative disorders and cancer. Collectively, these findings reinforce AMPK as a central metabolic node that aligns cellular behaviour with energetic demand. Continued investigation into its nutrient-sensing mechanisms holds promise for identifying new strategies to restore metabolic balance in disease.
