Influence of dural attachment on remnant progression after subtotal resection in WHO grade 1 meningioma.
Article in Acta neurochirurgica, 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
purposeMeningioma resection remains partial in over 25% of cases, with few known predictors of residual disease progression. This study aims to assess if dural attachment, identified on postoperative imaging, influences meningioma progression following subtotal resection.
methodsA retrospective cohort design was applied to patients who underwent subtotal meningioma resection at our institution. MRI data collected over time included remnant volumes, surface areas of contact with dura and signal intensity ratios. Progression was defined as an increase in remnant volume of at least 25%.
resultsSixty-one (61) remnants in 59 patients were followed for an average of 71.1 months postoperatively. Mean preoperative tumor volume and first remnant volume were 30.01 cm
conclusionThe degree of meningioma remnant attachment to dura appears associated with progression. Reduction of dural involvement in residual disease intentionally left in place may be considered when appropriate, with further studies needed to refine surgical considerations.
