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

introductionMeningiomas comprise 33% of all CNS tumors. The World Health Organization (WHO) describes meningiomas as benign (BM), atypical (AM), and malignant/anaplastic (MM). High-grade meningiomas such as AMs and MMs are more aggressive, recur more frequently, and portend a worse prognosis than BMs. Currently, the standard treatment for high-grade meningiomas, especially AMs, is ill-defined. In particular, the benefit to survival outcomes of adjuvant radiotherapy post-surgical resection remains unclear. In this study, we investigated the effect of adjuvant radiotherapy (ART) post-surgery on survival outcomes compared to surgery alone for high-grade meningiomas.

methodsPRISMA guidelines were a foundation for our literature review. We screened the PubMed database for studies reporting overall survival (OS), progression free survival (PFS), and tumor recurrence for intracranial, primary AM and MMs treated with surgery+ART or surgery alone. Fixed and random effect models compared tumor control rate for AM aforementioned groups.

resultsMean 5-year PFS was 76.9% for AM (surgery+ART) and 55.9% for AM (surgery alone) patients. Mean 5-year OS was 81.3% and 74% for AM (surgery+ART) and AM (surgery alone) groups, respectively. Overall, the mean 5-year PFS for aggregated high-grade meningiomas AM+MM (surgery+ART) was 67.6%. Fixed effect models revealed tumor control rate as 76% for AM (surgery+ART) and 69% for AM (surgery alone) groups. ART induced toxicity incidence ranged from 12.0% to 35.5% for AM and MM patients.

conclusionsOur analysis suggests that (surgery+ART) may increase PFS, OS, and tumor control rates in high-grade meningiomas. However, further studies involving surgery+ ART should be conducted to fully evaluate the ideal radiosurgical candidate, modality, and dosage.
