Intravascular Large B-Cell Lymphoma Presenting as Recurrent Cryptogenic Strokes: A Diagnostic Challenge.
Article in Case reports in hematology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Intravascular large B-cell lymphoma (IVLBCL) is a rare malignancy and is a challenging diagnosis to make given its varied clinical presentation. Here, we present the case of a 69-year-old male who presented with multiple cryptogenic strokes. Despite multiple hypercoagulable and malignancy workups, no etiology was identified, with multiple CT scans negative for any masses. Ultimately, a vascular abnormality was noted on a CTA of the head and neck, and IVLBCL was diagnosed on biopsy. The patient was initiated on R-CHOP and had improvement in his neurological status after the initiation of chemotherapy, and his ClonoSeq MRD testing is negative. This case is of interest given the lack of imaging findings for this patient prior to diagnosis as all of his CT scans were negative, making it a challenge to diagnose him as well as monitor his response to treatment. Additionally, his case highlights the importance of ClonoSeq MRD testing, which allows for the detection of even minimal amounts of disease in tracking response to treatment.
