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 68-year-old woman visited a gynecological clinic complaining of abdominal distension and pain. A large immobile tumor was palpable in the upper left abdominal area. Computed tomography showed an ovarian tumor measuring 20 cm in diameter anterior to the left kidney. A barium enema revealed that the descending colon was narrow, with a wall that was irregularly transformed by the tumor. Cytoreductive debulking surgery was performed. A histological examination demonstrated squamous cell carcinoma arising from a mature cystic teratoma of the ovary. The descending colon was invaded by cancer cells up to the mucosal tissue, and four lymph nodes were metastatic. After surgery, she received eight cycles of adjuvant chemotherapy. After the last treatment, she has been free of the disease for longer than 18 years. We describe the clinical characteristics of this case and speculate on the reason for the long-term survival.
