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.
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
Carcinosarcoma is a malignant tumor composed of both epithelial and mesenchymal malignant tumor components. A 78-year-old man was transferred to our hospital because of hematemesis and tarry stool. An emergency gastrointestinal endoscopic examination revealed active bleeding from an ulcerative lesion on the posterior wall of the gastric body; endoscopic hemostasis was successfully performed. A gastrointestinal endoscopy performed two months later showed a polypoid lesion at the same place where the ulcer had been. The biopsy specimen was histologically diagnosed as well to moderately differentiated tubular adenocarcinoma. The patient underwent a laparoscopic distal gastrectomy with D2 lymph node dissection under a diagnosis of gastric adenocarcinoma. A 28 × 15 mm polypoid tumor was resected from the gastric body, and was found on microscopic examination to consist of both carcinoma and sarcoma components, showing atypical spindle cells, which were positive for α-smooth muscular actin, calponin, and h-caldesmon, but negative for CD34, CD117 (c-kit), desmin, and dog 1. These findings led to a diagnosis of gastric carcinosarcoma. The tumor was confined to the mucous membrane. Lymph node metastasis was found in one node and contained only the carcinoma component. The postoperative course was uneventful. The patient lived without recurrence for 2 years. Carcinosarcoma of the stomach is a rare tumor with high malignant potential and poor prognosis. Careful follow up is required for early detection of any recurrence.
