1 · What the graph read from it

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.

2 · The registry

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

Small-cell lung carcinoma (SCLC) associated with cystic airspaces is rare. We describe the case of a 68-year-old man who was referred to our hospital because of a cystic lesion detected on chest radiography. Initial computed tomography revealed a small nodule abutting the cystic airspace due to paraseptal emphysema in the right lower lobe. Histopathological examination of lymphadenopathy indicated SCLC. Postchemotherapy, recurrence appeared as a thick-walled cystic airspace with an exophytic nodule along the cyst wall, mimicking pneumonia. Additional chemotherapy, but not antibiotic therapy, led to a reduction in the wall thickness and nodules. This case emphasizes unresponsiveness to antibiotic therapy, especially in patients with risk factors, highlighting the diagnostic pitfall that may delay timely cancer treatment.
