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

Organellar membranes feature bespoke lipid compositions; however, the enzymes that craft these compositions and the functional implications these lipids exert on membrane protein organization and activity are insufficiently understood. Here, we discover that the inner mitochondrial membrane protein Fmp30p, a member of the metallo-β-lactamase superfamily, displays phospholipase type D activity toward phosphatidylinositol (PI)-a notable mitochondrial membrane component with unclear functional roles. FMP30 deletion caused substantial and specific elevation of PI species in purified mitochondria. Augmenting mitochondrial PI levels in this way, or by targeting established PI-modifying enzymes to the organelle, increased coenzyme Q (CoQ) biosynthesis concomitant with elevated expression of CoQ-related enzymes and enhanced CoQ metabolon formation. Collectively, our work establishes Fmp30p as a mitochondrial PI phospholipase related to CoQ biology and reveals the broader importance of inner membrane PI in regulating mitochondrial function.
