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 actions and interactions of dihydropyridines (DHPs) and ethanol on sinus node (SN) automaticity were studied using rat sinoatrial preparations superfused with Tyrode's solution at 37 degrees C. Intracellular microelectrodes were used to monitor SN rate (SNR). The automaticity of the SN was not affected by nimodipine 10(-10) M, but it was depressed by a higher concentration of this calcium antagonist (10(-8) M). The racemic compound (+/-)Bay K 8644 had a dose-dependent biphasic chronotropic action: At 10(-8) M it decreased the SNR, while at 10(-7) M it increased the SNR. The negative component was blocked by atropine. A small concentration of ethanol (1.8 x 10(-2) M) had a positive chronotropic effect on the SN, and this action was blocked by nimodipine 10(-10) M. This small concentration of ethanol did not modify the chronotropic effects of either of the DHPs. A higher concentration of ethanol (5.3 x 10(-2) M) did not by itself affect the SNR, but it antagonized the chronotropic actions of the two DHPs.
