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

Calcified pericardial cysts are exceedingly rare, and cysts containing caseous material are scarcely reported. We describe a giant calcified pericardial cyst causing right ventricular compression and heart failure symptoms. Imaging demonstrated a large calcified pericardial mass abutting the right ventricle and atrioventricular groove. Surgical resection via median sternotomy with anterior pericardiectomy was performed. Intraoperatively, thick caseous material was found within a heavily calcified cyst wall. Histopathology revealed a fibrous cyst wall without epithelial lining and no evidence of malignancy or granulomatous inflammation. Post-resection transoesophageal echocardiography confirmed relief of right ventricular compression with preserved function. This case highlights diagnostic challenges and surgical considerations of complex calcified pericardial cysts with atypical intracystic contents.
