1 · What the graph read from 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.

2 · The registry

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

backgroundPediatric meningiomas (PMs) are rare central nervous system tumors, accounting for 1-5% of all meningiomas, and differ from adult meningiomas in clinical, histopathological, and molecular features. Current guidelines primarily focus on adults, leaving a gap in evidence-based management for PMs. This study presents the largest meta-analysis of longitudinal individual patient data (IPD) to date, addressing progression-free survival (PFS) and overall survival (OS) in pediatric patients.

methodsData from 20 studies (2011-2023), including 1010 pediatric meningioma cases, were analyzed to assess PFS and OS stratified by WHO grade, NF1/NF2 status, extent of resection (EOR), and adjuvant radiotherapy. Longitudinal survival data were reconstructed from Kaplan-Meier curves using IPD extraction methods.

resultsPMs affect males and females nearly equally (52.1% vs. 47.9%). WHO grade 3 tumors had significantly shorter PFS (72.1 months) compared to grades 1 (209.8 months) and 2 (137.5 months) (p < 0.001). No significant OS difference between WHO grades 1 and 2 PMs were observed. NF1- and NF2-associated tumors showed shorter PFS (59.7 and 138.4 months) than sporadic cases (180.6 months) (p = 0.02). GTR significantly improved PFS (113.8 vs. 40.1 months, p < 0.001) and OS (602.9 vs. 173.8 months, p < 0.001). Radiotherapy enhanced PFS (72.5 vs. 23.8 months, p = 0.009) and OS (140.7 vs. 63.0 months, p = 0.002) in grade 3 tumors but not in WHO grade 2 PMs (p = 0.43).

conclusionsThis largest meta-analysis highlights the critical roles of GTR and adjuvant radiotherapy in improving outcomes for high-grade PMs and underscores the urgent need for pediatric-specific management guidelines based on robust longitudinal data.
