Analytical validation of the Belay Vantage™ assay for evaluation of MGMT promoter methylation using enzymatically converted tumorDNA from cerebrospinal fluid.
Article in Cancer genetics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
MGMT promoter methylation status (hypermethylation) is one of the strongest prognostic and predictive biomarkers in glioblastoma (GBM) and is associated with a more favorable response to alkylating chemotherapies such as Temozolomide (TMZ). Additionally, it is associated with pseudo progression in GBM, a phenomenon in which early radiographic changes after treatment are indicative of possible tumor recurrence though on histological examination it is consistent with treatment effect. Current methods for evaluation of MGMT promoter methylation status are limited to tumor tissue, requiring invasive biopsy or surgery, prompting the need for a liquid biopsy-based assay to expand and manage therapeutic interventions. The Belay Vantage™ assay evaluates MGMT promoter methylation status in cerebrospinal fluid (CSF) of individuals with known or suspected central nervous system tumors using low input DNA. The assay uses quantitative polymerase chain reaction (qPCR) on DNA extracted from CSF after enzymatic conversion and has an analytical sensitivity of 95.5 % and specificity of 100 %.
