Increased carbohydrate antigen 19-9 expression in a thymic neuroendocrine tumor.
Article in Thoracic cancer, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Here, we report a case of carbohydrate antigen (CA) 19-9-producing mediastinal neuroendocrine tumor (NET) (atypical carcinoid). A 54-year-old woman with no specific relevant medical history was referred to our hospital because of increased CA19-9 (95.3 U/ml) detected on health screening. Chest computed tomography (CT) revealed an anterior mediastinal mass without localized lymphadenopathy. Thoracic surgery was performed and the histopathological diagnosis was thymic CA19-9-positive NET. The patient developed mediastinal lymph node metastasis at 1 year (CA19-9: 413 U/ml) and multiple bone metastases 4 years (CA19-9: 2303 U/ml) after surgery. Increased CA19-9 levels paralleled the clinical courses of relapse. To our knowledge, this is the first report of CA19-9-producing thymic NET.
