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

Takotsubo cardiomyopathy (TCM) has gained global recognition as a unique cardiovascular disease that mimics acute myocardial infarction. Since its initial description, more than three decades ago, we have significantly advanced our understanding of diagnosing, treating, and prognosticating this reversible cardiovascular phenomenon. However, the pathophysiological explanation behind its selective involvement of the left ventricle (LV), predominantly the LV apex in poorly understood. In this brief review on differential distribution of the adrenergic nerve (AN) and cholinergic nerve (CN) in the normal human heart, we try to extrapolate an idea of poor CN distribution in the LV apex as an associated factor augmenting microcirculatory dysfunction due to an unopposed AN activity from the catecholamine surge, as a plausible explanation for this characteristic phenomenon.
