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

K(ATP) channels couple the intracellular energy state to membrane excitability and regulate a wide array of biologic activities. K(ATP) channels contain a pore-forming inwardly rectifying potassium channel and a sulfonylurea receptor regulatory subunit (SUR1 or SUR2). To clarify the role of K(ATP) channels in vascular smooth muscle, we studied Sur2 gene-targeted mice (Sur2(-/-)) and found significantly elevated resting blood pressures and sudden death. Using in vivo monitoring, we detected transient, repeated episodes of coronary artery vasospasm in Sur2(-/-) mice. Focal narrowings in the coronary arteries were present in Sur2(-/-) mice consistent with vascular spasm. We treated Sur2(-/-) mice with a calcium channel antagonist and successfully reduced vasospastic episodes. The intermittent coronary artery vasospasm seen in Sur2(-/-) mice provides a model for the human disorder Prinzmetal variant angina and demonstrates that the SUR2 K(ATP) channel is a critical regulator of episodic vasomotor activity.
