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 25-year-old male was admitted to the neurological intensive care unit for neurologic deterioration, likely caused by a paraneoplastic syndrome secondary to testicular malignancy. He experienced spontaneous rupture and hemorrhage of his testicular mass arising from an undescended testis while admitted. The tumor was excised, revealing a mixed germ cell tumor. Serum tumor markers began to rise after 4 cycles of chemotherapy. Surveillance scans 32 weeks after mass rupture revealed numerous tumor deposits throughout his peritoneum concerning for teratoma. We review a case of intraperitoneal metastasis of a testicular mixed germ cell tumor following intra-abdominal mass rupture.
