Location pattern of recurrence of fully resected grade 1 meningiomas.
Article in Acta neurochirurgica, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
objectiveMeningiomas can lead to significant morbidity and mortality and have recurrence potential. While previous studies have focused on calculating recurrence risk, the precise location of the recurrence has not been delineated. This study aimed to investigate the spatial clustering pattern of recurrence relative to the original surgical bed for surgically treated Simpson Grade I-III, WHO Grade 1 meningiomas.
methodsPatients diagnosed with grade 1 meningiomas and treated with surgical resection with subsequent recurrence were reviewed. Patient demographics, clinical outcomes, and radiographic characteristics were collected. Radiological images were analyzed to determine the location of recurrence relative to the initial tumor. We characterized recurrence as type A (within the surgical bed), type B (outside of the surgical bed, within 1 cm from the site), and type C (distal ≥ 1 cm of the resection site).
resultsForty-two cases met the inclusion criteria. Twelve patients (29%) were male, and 30 (71%) were female. Median age at first treatment was 47 years, with 5.2 ± 3.4 years until recurrence. Recurrence rate was 54.7% at 5 years and 90.4% at 10 years. Twenty-eight patients (66.7%) had a type A recurrence, 11 (26.1%) had a type B recurrence, and 3 (7.1%) had a type C recurrence.
conclusionsOur series demonstrates that while lesions often recur within the original lesion site, a significant portion recurs beyond the surgical bed. This highlights the substantial possibility of recurrence outside the resection cavity for fully excised benign meningiomas, which may aid in understanding disease progression and in guiding adjuvant therapy.
