Antiepileptic drugs failed to prevent initial seizures or improve survival outcomes in patients with primary CNS lymphoma.
Observational study in Scientific reports, 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
This study examined the prevalence, risk factors, and prognosis of epilepsy in patients with primary central nervous system lymphoma (PCNSL) and explored the necessity of prophylactic antiepileptic treatment in this population. In this retrospective, observational, single-center study, we analyzed clinical data from PCNSL patients who were diagnosed at our institution between January 2018 and April 2023. The cohort comprised 214 patients with PCNSL (with a median age of 62 years), of which 128 (47.6%) patients were male. Epilepsy was observed in 16.82% (36/214) of the patients, with 9.35% (20/214) presenting with seizures as the initial symptom. Cortical involvement was significantly associated with seizures (OR = 9.512, 95% CI 3.870-23.381; p = 0.036). Other potential risk factors included an edema zone > 1 cm around the lesion and PIM1 wild-type status. Antiepileptic drugs (AEDs) neither reduced seizure incidence (8.11% with AEDs vs. 8.43% with no AEDs, p = 0.970) nor improved PFS (HR = 0.613, 95% CI 0.338-1.109; p = 0.106). Therefore, AEDs should not be used as preventive measures in this population.
