Chronic Lymphocytic Leukemia With Leptomeningeal Involvement Presenting as an Acute Encephalopathy.
Article in The Permanente journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Introduction Chronic lymphocytic leukemia (CLL) is the most common adult leukemia in Western countries. Extramedullary involvement in the central nervous system (CNS) is a rare complication of the disease, and less than 200 cases have been reported. We report a case of leptomeningeal involvement of CLL that presented as an acute encephalopathy. Case presentation A 76-year-old man with treatment-naïve, Rai stage 0 CLL presented with altered mental status. Cerebrospinal-fluid studies, including flow cytometry, confirmed the leptomeningeal involvement of the previously diagnosed CLL. Surveillance imaging and lab studies showed no evidence of disease progression or Richter's transformation. One-time intrathecal methotrexate resulted in transient improvement of his mental status. Conclusion CLL patients with new-onset neurologic manifestations should be evaluated for the CNS involvement of the neoplasm via brain imaging and cerebrospinal-fluid flow cytometry. This CNS involvement of CLL is associated with poor clinical outcomes. Intrathecal treatment with methotrexate, cytarabine, and steroid may improve neurologic symptoms.
