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
Although relatively rare, cardiac metastases represent a significant clinical challenge because of their impact on cardiac function and overall patient prognosis. This case presents a rare and atypical presentation of a patient with ventricular arrhythmia revealing a metastatic cancer in the heart. A 59-year-old man with lung cancer was admitted for chest tightness and episodes of syncope. Cardiac high-sensitivity troponin was negative. An electrocardiogram showed runs of sustained ventricular tachycardia, whereas an echocardiogram revealed hypokinesis in the anterolateral/anterior left ventricular (LV) walls. Coronary angiogram was normal. Cardiovascular magnetic resonance imaging (CMR) showed a large inhomogeneous lesion of the LV midanterior wall with a peripheral component of hyperenhancement and a central core with clear hyposignal, adjacent to the pulmonary carcinomatous mass. Because the patient had a poor short-term prognosis, medical treatment and palliative care were proposed. In the management of patients with myocardial metastasis, CMR is important in the diagnostic workup of cardiac masses, prognosis and treatment, negative troponin, and ventricular arrhythmia.
