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 syndrome (TTS) is a transient cardiomyopathy that is often associated with cerebrovascular diseases. Earlier studies have supported the concept that the cardiovascular system is regulated by a central autonomic network (CAN) consisting of the insular cortex (IC), anterior cingulate gyrus and amygdala. We report the case of a 79-year-old female diagnosed with a mid-ventricular variant of TTS concomitant with right IC ischaemic stroke. After 12 h of hospitalization, she experienced a sudden collapse. Rapid cardiopulmonary resuscitation resulted in a return of spontaneous circulation. Subsequent left ventriculography revealed akinesis in the mid-portion of the left ventricle with vigorous contraction of the basal and apex segment. Two weeks after admission, cardiac ultrasound showed improved left ventricular contraction. Right IC ischaemia in this patient might have been associated with a dysregulation of the CAN and subsequent increased sympathetic nervous system activity that triggered TTS.
