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

Background: Primary pulmonary extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) localized in the trachea and bronchus is rare and diagnostically challenging due to nonspecific clinical and radiological features. Case description: We present two cases of primary endobronchial MALT lymphoma incidentally diagnosed via bronchoscopy. We assessed the characteristic bronchoscopic finding of endobronchial MALT lymphoma, radiological examinations and overall treatment strategies. Conclusion: This study highlights the importance of considering endobronchial MALT lymphoma as a potential diagnosis. A thorough bronchoscopic evaluation of the central airways, along with appropriate biopsy of suspicious lesions, is crucial. Endobronchial MALT lymphoma should be suspected when targeting multiple widely stalked and smooth submucosal nodules or protrusions, mainly located in the central airways.
