Chronic bronchitis with fungal infection presenting with marked elevation of serum carbohydrate antigen 19-9: a case report.

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
Carbohydrate antigen 19-9 (CA19-9) is the most frequently applied serum tumor marker for diagnosis of cancers in the digestive organs. However, some patients with benign diseases can have elevated serum levels of CA19-9 as well. The current study presents a 55-year-old female who was admitted to our hospital for further evaluation of a nodular cavity shadow in the right lower lobe and clarification of the cause of the marked elevation of serum CA19-9 levels. Abdominal MRI and gastrointestinal endoscopy did not find any malignancy. As lung cancer cannot be excluded in this patient, a video-assisted thoracoscopic surgery was carried, intraoperative and postoperative biopsy analysis both suggested chronic bronchitis with fungal infection (due to Histoplasma capsulatum or Penicillium marneffei) and organization. Immunohistochemistry showed marked positive staining for CA19-9 in the damaged lung tissue. The CA19-9 levels quickly returned to the normal range following lobe resection. Therefore, the marked elevation of serum CA19-9 levels, in this case, may have resulted from the chronic bronchitis with fungal infection.
