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

A 69-year-old man visited our hospital due to left pleural effusion by chest X-ray. Thoracentesis indicated hemothorax and the specimen of pleural effusion confirmed malignant cells. Because anemia became apparent due to persistent bloody pleural effusion, thoracoscopic hemostasis was performed with surgical biopsy for a tumor extending beyond the visceral pleural of the left upper lobe and the patient was finally diagnosed as having a primary pleomorphic carcinoma. Then, the tumor rapidly shrunk and completely resolved in three months. Our case indicates that spontaneous regression possibly develops following thoracoscopic surgery for hemothorax in pulmonary pleomorphic carcinoma patients.
