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: IgG4-related disease (IgG4-RD) is a chronic fibro-inflammatory condition that can mimic malignancy due to its tumorous lesions. Marginal zone lymphoma (MZL), a low-grade B cell lymphoma, may occasionally arise in the context of chronic immune stimulation. The synchronous occurrence of IgG4-RD and MZL is rare and diagnostically challenging. Case Report: We report the case of a 39-year-old male with right hemiplegia and aphasia, initially suspected to have a meningioma based on magnetic resonance imaging (MRI) findings. Histopathology following surgical resection revealed features consistent with IgG4-RD. Subsequently, [ Discussion: The coexistence of IgG4-RD and MZL raises important considerations regarding shared immunopathogenic mechanisms. Dual molecular imaging with FDG and FAPI (fibroblast activating protein inhibitor)-based radiotracers proved essential in discriminating between inflammatory and neoplastic components of disease, enabling accurate diagnosis and guiding appropriate management. Conclusion: This case highlights the value of [
