Behavioral Changes as the Initial Presentation of Primary Central Nervous System Lymphoma: A Case Report.
Article in Cureus, 2025. 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
Brain tumors typically present with headaches, nausea, vomiting, seizures, or focal neurological deficits. However, neuropsychiatric manifestations, such as personality change and behavioral disturbance, may be the earliest signs, particularly when the frontal or temporal lobes are involved. We describe a 69-year-old man who presented repeatedly to his general practitioner (GP) with progressive behavioral changes and intermittent headaches. Initial investigations were unremarkable, and he received cognitive-behavioral therapy without improvement. He later developed facial deviation and limb numbness. Computed tomography (CT) of the head revealed a large, right-sided, space-occupying lesion, subsequently confirmed by magnetic resonance imaging (MRI) to be an intracranial tumor. Histopathology following biopsy confirmed primary central nervous system lymphoma (PCNSL). This case highlights the importance of considering intracranial pathology in patients with persistent or unexplained behavioral changes and underscores the role of early neuroimaging in preventing diagnostic delays.
