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

Pleural effusion following chimeric antigen receptor (CAR) T-cell therapy is typically transient, bilateral, and associated with cytokine release syndrome. We herein report persistent unilateral massive pleural effusion with CAR T-cell infiltration in a 34-year-old man with refractory primary mediastinal large B-cell lymphoma involving pleural lesions treated with axicabtagene ciloleucel. Flow cytometry confirmed CAR T-cell infiltration into the pleural fluid. Although temporarily improved by corticosteroids, the effusion persisted for several months but eventually resolved spontaneously. Physicians should consider CAR T-cell infiltration in persistent unilateral pleural effusion after CAR T-cell therapy, emphasizing the importance of flow cytometry for the diagnosis and potential spontaneous resolution without corticosteroids.
