11,12-Epoxyeicosatrienoic acid induces vasodilator response in the rat perfused mesenteric vasculature.
Article in Autonomic & autacoid pharmacology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
Epoxyeicosatrienoic acids (EETs) are endogenous ligands that undergo hydrolysis by soluble epoxide hydrolase (sEH). The responses of 11, 12-EET in comparison with other vasodilator agonists including carbachol and sodium nitroprusside (SNP) were investigated. The effect of 1-cyclohexyl-3-dodecyl urea (CDU), a sEH, was tested on the vasodilator effect induced by 11, 12-EET in the perfused mesenteric beds isolated from normo-glycaemic and type-1 STZ-diabetic rats. In the perfused mesenteric beds of control and diabetic animals, 11, 12-EET produced vasodilation in a dose-dependent manner. The vasodilator response induced by 11, 12-EET was significantly decreased in tissues obtained from diabetic animals, but this was significantly corrected through inhibition of sEH. The effects of nitric oxide synthase inhibitor, cyclo-oxygenase inhibitor, specific potassium channel inhibitors, soluble guanylyl cyclase inhibitor and transient receptor potential channel V4 inhibitor, on vasodilator response to 11, 12-EET were investigated. In tissues isolated from control animals, vasodilator responses to 11, 12-EET were not inhibited by acute incubation with l-NAME, l-NAME with indomethacin, glibenclamide, iberiotoxin, charybdotoxin, apamin or ODQ. Incubation with the transient receptor potential channel V4 inhibitor ruthenium red caused significantly reduced vasodilator responses induced by 11, 12-EET. In conclusion, results from this study indicate that 11, 12-EET has a vasodilator effect in the perfused mesenteric bed, partly through activation of vanilloid receptor. A strategy to elevate the levels of EETs may have a significant impact in correcting microvascular abnormality associated with diabetes.
