Radiation-induced meningiomas (RIM) in adults: A single-centre retrospective experience.
Article in Brain & spine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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: Radiotherapy of central nervous system (CNS) is treatment against many paediatric cancers, even if it is a well-recognized risk factor for meningioma formation. An increased risk of developing secondary brain tumors like radiation-induced meningiomas (RIM) is related to irradiated patients. Research question: This retrospective study aims to present RIM cases treated in a single tertiary-hospital in Greece and compare the results with international literature and cases of sporadic meningiomas. Materials and methods: A single-centre retrospective study of all patients diagnosed between January 2012 and September 2022 with RIM after having been irradiated in CNS for paediatric cancer was undertaken through hospital's electronic record and clinical notes, identifying baseline demographics and latency period. Results: Thirteen patients were identified with RIM diagnosis after receiving irradiation for Acute Lymphoblastic Leukaemia (69.2%), Premature Neuro-Ectodermal Tumour (23.1%), and Astrocytoma (7.7%). Median age at irradiation was 5 years old and 32 years old at RIM's presentation. The latent period from irradiation to meningioma diagnosis was 26.23 ± 5.96 years. After surgical excision, histopathologic results showed grade I meningiomas in 12 out of thirteen cases, while only one atypical meningioma was diagnosed. Conclusion: Patients who underwent CNS-radiotherapy in childhood for any condition have an increased risk of developing secondary brain tumors such as radiation-induced meningiomas. RIMs resemble sporadic meningiomas in symptomatology, location, treatment, and histologic grade. However, long-term follow-up and regular check-ups are recommended in irradiated patients due to short latency period from irradiation to RIM development, which means younger age patients than those with sporadic meningiomas cases.
