A case of diffuse aspiration bronchiolitis due to oesophageal stenosis after radiation therapy.

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 66-year-old woman was hospitalized for recurrent pneumonia twice in 1 year. After treatment for pneumonia, chronic coughing, sputum and low-grade fever continued, so she was referred and admitted to our hospital for investigation. Chest computed tomography revealed a lung infiltrative shadow and diffuse centrilobular micronodules. Histological findings from transbronchial lung biopsy showed chronic inflammation and giant cells in the bronchiole. These findings were compatible with diffuse aspiration bronchiolitis (DAB), which is characterized by chronic inflammation of the bronchioles caused by recurrent aspiration of foreign bodies. Oesophagogastroduodenoscopy revealed stenosis of the oesophageal entrance, which was thought to be caused by radiation therapy for hypopharyngeal cancer 20 years before. Antibiotic treatment ameliorated the centrilobular nodule shadow. After discharge, there was no recurrence. This is the first case report of DAB resulting from oesophageal stenosis associated with hypopharyngeal cancer and will serve as an educational case.
