Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia: an under-recognized entity-a report of two cases.

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
Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare pulmonary disorder that is classified as a pre-invasive lesion. It can also be present in association with chronic lung diseases. We present two cases of DIPNECH, which were picked up incidentally only on histopathology. A 29-year-old male presented with a history of longstanding cough with expectoration. A computed tomography (CT) scan showed bronchiectasis in the left lung. Histopathological evaluation of the pneumonectomy specimen revealed nests of proliferating, non-infiltrating neuroendocrine cells. Our second patient was a 38-year-old female with chronic cough and expectoration with recent exacerbation. CT scan showed cystic bronchiectasis in the left lower lobe; hence, a lobectomy was performed. On histopathology, nests of non-infiltrating neuroendocrine cells were noted. A diagnosis of DIPNECH with bronchiectasis was offered to both patients, and they have been on follow-up ever since. DIPNECH is a diagnostic and therapeutic quandary requiring a high index of suspicion for its detection and effective surveillance.
