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

A high-NaCl diet induces renal medullary cyclooxygenase (COX)2 expression, and selective intramedullary infusion of a COX2 inhibitor increases blood pressure in rats on a high-salt diet. The present study characterized the specific prostanoid contributing to the antihypertensive effect of COX2. C57BL/6J mice placed on a high-NaCl diet exhibited increased medullary COX2 and microsomal prostaglandin E synthase1 (mPGES1) expression as determined by immunoblot and real-time PCR. Cytosolic prostaglandin E synthase and prostacyclin synthase were not induced by the high-salt diet. Immunofluorescence showed mPGES1 in collecting ducts and interstitial cells. High salt increased renal medullary PGE(2) as determined by gas chromatography/negative ion chemical ionization mass spectrometry. The effect of direct intramedullary PGE(2) infusion was examined in anesthetized uninephrectomized mice. Intramedullary PGE(2) infusion (10 ng/h) increased urine volume (from 3.3 +/- 0.6 to 9.5 +/- 1.6 mul/min) and urine sodium excretion (0.11 +/- 0.02 to 0.32 +/- 0.05 mueq/min). To determine which E-prostanoid (EP) receptor(s) mediated PGE(2)- dependent natriuresis, EP-selective prostanoids were infused. The EP(2) agonist butaprost produced natriuresis (from 0.06 +/- 0.02 to 0.32 +/- 0.05 mueq/min). The natriuretic effect of intramedullary PGE(2) or butaprost was abolished in EP2-deficient mice, which exhibit NaCl-dependent hypertension. In conclusion, a high-salt diet increases renal medullary COX2 and mPGES1 expression, and increases renal medullary PGE(2) synthesis. Renal medullary PGE(2) promotes renal sodium excretion via the EP2 receptor, thereby maintaining normotension in the setting of high salt intake.
