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

Phospholipase D (PLD), a phospholipid phosphohydrolase, catalyzes the hydrolysis of phosphatidylcholine and other membrane phospholipids to phosphatidic acid (PA) and choline. PLD, ubiquitous in mammals, is a critical enzyme in intracellular signal transduction. PA generated by agonist- or reactive oxygen species (ROS)-mediated activation of the PLDI and PLD2 isoforms can be subsequently converted to lysoPA (LPA) or diacylglycerol (DAG) by phospholipase A1/A2 or lipid phosphate phosphatases. In pulmonary epithelial and vascular endothelial cells, a wide variety of agonists stimulate PLD and involve Src kinases, p-38 mitogen activated protein kinase, calcium and small G proteins. PA derived from the PLD pathway has second-messenger functions. In endothelial cells, PA regulates NAD[P]H oxidase activity and barrier function. In airway epithelial cells, sphingosine-1-phosphate and PA-induced IL-8 secretion and ERKI/2 phosphorylation is regulated by PA. PA can be metabolized to LPA and DAG, which function as first- and second-messengers, respectively. Signaling enzymes such as Raf 1, protein kinase Czeta and type I phosphatidylinositol-4-phosphate 5-kinase are also regulated by PA in mammalian cells. Thus, PA and its metabolic products play a central role in modulating endothelial and epithelial cell functions.
