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

We report a case of a 77-year-old man presenting with bilateral hemothorax, hemoptysis, and multiple bilateral pulmonary nodules and lung infiltrates. Histopathological and immunohistochemical analysis of a surgically resected nodule revealed epithelioid angiosarcoma, and the overall radiological and operative findings favored pulmonary origin. No other primary sites outside the thorax could be identified. The patient was planned for palliative chemotherapy, but his condition deteriorated, and he died before treatment could be initiated. Angiosarcoma is a rare and highly aggressive endothelial malignancy, most commonly affecting the skin and subcutaneous tissue of the head and neck. Primary pulmonary angiosarcoma is extremely uncommon; pulmonary involvement more often occurs through metastatic spread. When angiosarcoma involves the lungs as a primary neoplasm, it may present with multiple nodules, hemorrhagic lesions, or diffuse infiltrative patterns, frequently leading to hemoptysis and respiratory symptoms. Clinical course can be rapid, and prognosis is poor, particularly in advanced thoracic disease.
