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

We assessed the anti-anginal effects of cilnidipine in comparison with those of nicardipine and nifedipine (1 and 10 µg/kg, n = 6 for each drug) or vehicle (n = 6) by using the vasopressin-induced angina model of rats. The administration of vasopressin (0.5 IU/kg, i.v.) to the rats depressed the S-wave level of the electrocardiogram reflecting the presence of subendocardial ischemia, whereas it significantly increased the mean blood pressure, resulting in the decrease of the heart rate and the prolongation of the PR interval possibly through a reflex-mediated increase in vagal tone. Cilnidipine suppressed the vasopressin-induced depression of the S-wave level in a dose-related manner, which was not observed by nicardipine or nifedipine. In addition, the low dose of cilnidipine hardly affected the vasopressin-induced pressor response, but it attenuated the negative dromotropic effect, suggesting N-type Ca
