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

Pacemaker atrioventricular (AV) rings, continuous with the AV node, have been shown to be present in the mammalian and avian hearts. There is conspicuous lack of electrophysiological data on the cardiac pacemakers in reptiles. We aimed to characterize the AV ring in the common lizard heart for the first time using conventional microelectrode technique. Detaching the sinoatrial (SA) area unmasked pacemaking in the AV junction. In all seven studied isolated AV ring preparations, we could record action potentials (APs) with characteristic diastolic depolarization, with a slow upstroke (dV/dt
