Carcinosarcoma ex pleomorphic adenoma of the parotid gland: a case report.
Article in Journal of surgical case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 ex pleomorphic adenoma is an extremely rare malignant neoplasm of the salivary gland that originates from a pre-existing benign tumor. Malignant transformation of the pleomorphic adenoma is extremely rare. The management of carcinosarcoma ex pleomorphic adenoma remains challenging because of its rarity, behavioral aggressiveness and resemblance to benign pleomorphic adenoma. Herein, we present the case of a 75-year-old male resident of Saudi Arabia with a history of a swelling in the right parotid gland for more than 25 years, which grew slowly with time. He underwent surgical removal with superficial parotidectomy. Afterward, histological examination of the resected tumor revealed features of carcinosarcoma, and he was diagnosed with carcinosarcoma ex pleomorphic adenoma. He presented again with recurrence of the tumor, which was managed with total parotidectomy and a combination of radiotherapy and chemotherapy. At 12-month follow-up, the patient showed no evidence of disease recurrence or distant metastasis.
