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

We hypothesized that normal vascular reactivity could be restored in vessels from hypercholesterolemic animals by exposing them to L-arginine, the precursor of endothelium-derived relaxing factor (EDRF). Basilar arteries were harvested from New Zealand white rabbits fed normal chow or that supplemented with 2% cholesterol for 10 wk. Vessels were cannulated for perfusion at physiologic pressure. Changes in vessel diameter were monitored by videomicroscopy. In comparison to normal vessels, those from hypercholesterolemic animals vasoconstricted more to KCl, endothelin (E), and 5-hydroxytryptamine (5-HT). Conversely, vasodilation to acetylcholine (ACh) (but not that to verapamil) was significantly impaired in the hypercholesterolemic animals. In vitro administration of L-arginine (3 mM) for 45 min normalized vasodilation to ACh and vasoconstriction to E, 5-HT, and KCl in the isolated vessels from hypercholesterolemic animals. This effect was stereospecific, since D-arginine had no effect. To conclude, these data confirm that hypercholesterolemia attenuates endothelium-derived relaxation, and enhances the sensitivity of these vessels to vasoconstrictors. In vitro administration of L-arginine normalized vascular reactivity of isolated vessels from hypercholesterolemic animals. Thus, hypercholesterolemia induces a reversible endothelial dysfunction that may be corrected by supplying the precursor of EDRF, L-arginine.
