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

The effects of ZD0947, a novel urinary bladder selective ATP-sensitive potassium channel (K(ATP) channel) opener, on carbachol-induced contractions of isolated guinea pig urinary bladder strips were investigated to compare its ability to relax norepinephrine-induced contraction of the aorta. Electrophysiological techniques were also utilized to compare the effects of ZD0947 on membrane currents between guinea pig detrusor and aortic myocytes. ZD0947 caused a significant reduction of the carbachol-induced contractile activity, demonstrating a biphasic relaxation (the first and second components). Although glibenclamide antagonized the effects of two components for the ZD0947-induced relaxation, gliclazide, a selective sulphonylurea receptor 1 (SUR1) antagonist, reduced the effects of the first component but not the second component of the ZD0947-induced relaxation. ZD0947 also reduced the norepinephrine-induced contraction of the aorta. ZD0947 reduced electrical excitability of detrusor smooth muscles, inhibiting spike discharges and also hyperpolarizing the membrane as measured with microelectrodes. In conventional whole-cell configuration, ZD0947 caused a glibenclamide-sensitive K(+) current (i.e., K(ATP) current) at a holding potential of -60 mV in guinea pig detrusor and aortic myocytes. The current density of ZD0947-induced K(ATP) currents in guinea pig detrusor myocytes was significantly larger than that in aortic smooth muscle cells. These results show that ZD0947 caused a significant relaxation through the activation of K(ATP) channels in detrusor muscle.
