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

Approximately 20% of patients with Takotsubo syndrome (TTS) develop complications such as left ventricular outflow tract obstruction (LVOTO). The published data suggest that a significant proportion of these patients have predisposing septal hypertrophy or sigmoid septum. However, the pathophysiology regarding this connection has not yet been fully elucidated. We herein present the case of a 75-year-old female patient with TTS complicated by LVOTO, which was successfully managed. During the follow-up, mild basal septal hypertrophy was observed. Subsequent exercise and dobutamine stress echocardiography were performed to reveal the mechanism of LVOTO in TTS.
