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.
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
Background: Takotsubo cardiomyopathy usually presents with acute reversible left ventricular apical hypokinesia and apical ballooning with basal hyperdynamic function. We describe an underreported case of Takotsubo cardiomyopathy (TCM), misinterpreted as apical hypertrophic cardiomyopathy (HCM) due to transient apical oedema in the recovery phase of the condition. Case summary: A 74-year-old Caucasian woman, presented to the emergency department complaining of retrosternal chest pain following, emotional stress. Her electrocardiogram (ECG) demonstrated poor R-wave progression in the right precordial leads raising the possibility of an anterior non-ST elevation myocardial infarction. High sensitivity troponin was elevated at 2232 ng/L, echocardiography demonstrating apical ballooning and left ventricular ejection fraction of 45%. Computed tomography coronary angiography revealed unobstructive coronary arteries. Cardiac magnetic resonance imaging (cMRI) demonstrated morphological features consistent with apical HCM. However, subsequent cMRI examination, illustrated resolution of the hypertrophic segments, with T1 parametric mapping and extracellular volume (ECV) favouring TCM over apical HCM. Discussion: Following emotional stress, takotsubo cardiomyopathy is understood caused by various mechanisms: catecholamine surge, inflammation, or transient ischaemia event leading to dysregulated cellular mechanisms. This results in myocardial oedema and increased wall stiffness leading to non-type 1 coronary plaque event-related regional wall motion abnormalities.In this instance, the initial two cMRI studies reported morphological features consistent with apical HCM, however, a subsequent examination demonstrated resolution of these features. The key to delineating these distinct pathologies lies in myocardial T1 times that exceeded what is normally observed in HCM, the absence of late gadolinium enhancement and ECV values which favour takotsubo cardiomyopathy.
