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

Immunohistochemical quantification of H3K27me3 was reported to distinguish meningioma patients with an unfavorable prognosis but is not yet established as a prognostic biomarker within WHO grade 3 meningiomas. We studied H3K27me3 loss in a series of biopsies from primary and secondary malignant meningioma to validate its prognostic performance and describe if loss of H3K27me3 occurs during malignant transformation. Two observers quantified H3K27me3 status as "complete loss", < 50% and > 50% stained cells in 110 tumor samples from a population-based consecutive cohort of 40 WHO grade 3 meningioma patients. We found no difference in overall survival (OS) in patients with > 50% H3K27me3 retention compared to < 50% in the cohort of patients with WHO grade 3 meningioma (Wald test p = 0.5). H3K27me3 staining showed heterogeneity in full section tumor slides while staining of the Barr body and peri-necrotic cells complicated quantification further. H3K27me3 expression differed without a discernible pattern between biopsies from repeated surgeries of meningioma recurrences. In conclusion, our results were not compatible with a systematic pattern of immunohistochemical H3K27me3 loss being associated with OS or malignant transformation of meningiomas and did not support H3K27me3 loss as a useful immunohistochemical biomarker within grade 3 meningiomas due to staining-specific challenges in quantification.
