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

In this study we describe the ability of two human urotensin-II (hU-II) derivatives [Pen5,Orn8]hU-II(4-11) and [Pen5,DTrp7,Orn8]hU-II(4-11) (urantide) to block hU-II-induced contractions in the rat isolated thoracic aorta. Both compounds competitively antagonized hU-II- induced effects with pKB=7.4+/-0.06 (n=12) and pKB=8.3+/-0.09 (n=12), respectively. In contrast, neither [Pen5,Orn8]hU-II(4-11) nor urantide (1 microm each) was able to modify noradrenaline- or endothelin 1-induced contractile effects. At micromolar concentrations, [Pen5,Orn8]hU-II(4-11) produced weak (< or =25% of hU-II maximum) agonist responses in the rat aorta, whereas urantide was totally uneffective as agonist up to 1 microm. In addition, [Pen5,Orn8]hU-II(4-11) and urantide displaced [125I]urotensin II from specific binding at hU-II recombinant receptors (UT receptors) transfected into CHO/K1 cells (pKi=7.7+/-0.05, n=4 and pKi=8.3+/-0.04, n=4, respectively). To our knowledge, urantide is the most potent UT receptor antagonist so far described, and might represent a useful tool for exploring the (patho)physiological role of hU-II in the mammalian cardiovascular system.
