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

backgroundThis report describes the clinical presentation and management of aruptured giant thoracic hydatid cyst in a young adult, highlighting the diagnostic and therapeuticchallenges associated with pulmonary echinococcosis, particularly in endemic regions. The caseemphasizes the importance of early recognition to prevent severe complications.

methodsA 22-year-old college student from Iran presented with progressive dyspnea, chest pain, fever, cough,and hemoptysis. Imaging studies, including chest radiography and computed tomography, wereperformed, revealing a giant cystic lesion in the left hemithorax with the pathognomonic "waterlily" sign. Surgical intervention via posterolateral thoracotomy was undertaken, involvingcomplete aspiration of the cyst, cavity cleansing, and chest tube placement.

resultsIntraoperative findings confirmed a giant ruptured hydatid cyst. The cyst was successfully excised, and the patient received postoperative albendazole therapy to prevent recurrence. Histopathological examination confirmed the diagnosis of Echinococcus granulosus infection. The patient's symptoms resolved following surgery, with no immediate postoperative complications.

conclusionRuptured pulmonary hydatid cysts can present with acute respiratory symptoms and characteristic imaging signs such as the "water lily" sign. Surgical removal remains the cornerstone of treatment, complemented by antiparasitic medication. In endemic areas, heightened clinical suspicion and prompt intervention are essential to reduce morbidityand prevent life-threatening hypersensitivity reactions.
