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

Proteases are involved in numerous essential biological processes including blood clotting, controlled cell death, and tissue differentiation. Prostasin, a glycosylphosphatidylinositol-anchored serine protease, has been identified as a potential regulator of the epithelial sodium channel (ENaC) function in the kidney, lung, and airways. ENaC is composed of three homologous subunits α, β, and, γ. The dual cleavage of α subunit by furin and γ subunit by prostasin and furin releases inhibitory segments from ENaC, leading to the channel activation. Protease nexin-1, an endogenous prostasin inhibitor, inhibits ENaC activity through the suppression of prostasin activity, strongly suggesting the possibility that a coordinated regulation of serine proteases and serine protease inhibitors plays a key role in the sodium handling in the kidney. Camostat mesilate (CM), a synthetic serine protease inhibitor, reduced prostasin activity and subsequently decreased ENaC current. Oral administration of CM to Dahl salt-sensitive rats resulted in a significant decrease in blood pressure with an elevation of the urinary sodium/potassium ratio. These findings suggest that synthetic serine protease inhibitors such as CM might represent a new class of antihypertensive drugs in patients with salt-sensitive hypertension.
