Gastric hamartomatous inverted polyps have high internal echoes: A case report.
Article in Radiology case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
A 58-year-old woman with an elevated lesion in the stomach was referred to our hospital. Gastroscopy showed a lobulated mass resembling a submucosal tumor. The tumor showed early enhancement on computed tomography. Endoscopic ultrasound showed a lobulated tumor with distinct borders, no attenuated posterior echoes, and high internal echoes. Fine needle aspiration biopsy pathologically showed normal gastric mucosa and spindle cells growing sparsely with SMA positivity and DOG1/S100 negativities, suggesting an inflammatory fibroid polyp. The patient, therefore, underwent laparoscopy endoscopy cooperative surgery to the gastric lesion. Postoperative pathological study showed downward mucosal proliferation into the submucosal layer in a lobulated manner with hyperplasia of the crypt epithelium. Some part of the lesion was located under the normal orthotopic gastric mucosa. These pathologic findings led us to the diagnosis of gastric hamartomatous inverted polyp (GHIP). In conclusion, endoscopy specialists should note that fibrous component-rich tumors have low internal echoes and attenuated posterior echoes, whereas GHIPs have high internal echoes and no attenuated posterior echoes.
