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

backgroundContractile dysfunction, hypertrophy, and cell death during heart failure are linked to altered Ca

methodsMice received 1-week infusions of AngII, bisperoxovanadium (1,10 phenanthroline), both, or saline via osmotic minipumps. We used mass spectrometry, super-resolution microscopy, electrophysiology, confocal imaging, immunoblot, echocardiography, and histology to assess phosphoinositide levels, L-type voltage-gated calcium channel Ca

resultsChronic AngII infusion caused widespread phosphoinositide imbalance, reducing phosphatidylinositol, phosphatidylinositol phosphate, phosphatidylinositol bisphosphate, and phosphatidylinositol (3,4,5)-trisphosphate levels. Ca

conclusionsThese findings reveal a complex interplay between phosphoinositide signaling, ion channel trafficking, and compensatory phospho-regulation in AngII-induced cardiac pathology. We establish phosphatidylinositol (3,4,5)-trisphosphate depletion as a critical link between chronic AngII signaling and cardiac dysfunction. The dissociation between persistent cellular remodeling and preserved organ function with PTEN inhibition reveals that cardioprotection occurs primarily through reduced fibrosis. PTEN inhibition, thus, emerges as a promising therapeutic strategy for heart failure associated with pathological renin-angiotensin system activation, with potential to complement existing therapies by targeting antifibrotic responses.
