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

Protease-activated receptor-2 (PAR2) is expressed in endothelial cells and mediates endothelium-dependent vasodilation. We hypothesized that PAR2 regulates tumor necrosis factor-alpha (TNF-α)-induced coronary arteriolar dysfunction in type 2 diabetic (db/db) mice. To test this, coronary arterioles from WT control, db/db, db/db mice treated with PAR2 antagonist FSLLRY-NH₂ (db/db+FSLLRY-NH₂) and db/db mice null for TNF (db(TNF-)/db(TNF-)) were isolated and pressurized (60 cmH₂O) without flow. Although vasodilation to the endothelium-independent vasodilator sodium nitroprusside (SNP) was not different among WT, db/db, db/db+FSLLRY-NH₂ and db(TNF-)/db(TNF-), endothelium-dependent acetylcholine (ACh)- and flow-mediated vasodilation were impaired in db/db mice but were enhanced in db(TNF-)/db(TNF-) mice and db/db mice treated with PAR2 antagonist. NOS inhibitor N (G)-nitro-L-arginine-methyl ester (L-NAME) significantly reduced ACh-induced dilation in WT, db(TNF-)/db(TNF-) and db/db+FSLLRY-NH₂, but did not alter the vasodilation in db/db mice. In contrast, cyclooxygenase (COX) inhibitor indomethacin (Indo) did not alter ACh-induced vasodilation in these four groups of mice. PAR2-activating peptide (PAR2-AP, 2-Furoyl-LIGRLO-am)-induced dilation was higher in db/db mice than that in WT, db(TNF-)/db(TNF-) and db/db mice treated with PAR2 antagonist. These effects were abolished by denudation, or in the presence of L-NAME or Indo. Protein expressions of TNF-α, PAR2, gp91(phox) and p47(phox) in the heart and isolated coronary arterioles were higher in db/db mice compared to WT mice. Administration of PAR2 antagonist to db/db mice reduced protein expression of TNF-α, gp91(phox) and PAR2. Protein expression of gp91(phox) and p47(phox) was lower in db(TNF-)/db(TNF-) compared to db/db mice. These results indicate that PAR2 plays a pivotal role in endothelial dysfunction in type 2 diabetes by up-regulating the expression/production of TNF-α and activating NAD(P)H oxidase subunit p47(phox).
