Identifying targeted cell-free DNA methylation regions in head and neck cancer via paired methylome analysis.
Article in Research square, 2024. 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
Despite the critical need, progress in developing cell-free DNA (cfDNA) liquid biopsy biomarkers for the diagnosis and risk stratification of head and neck squamous cell carcinoma (HNSC) has been limited. In this study, we present a comprehensive paired-sample differential methylation region (psDMR) analysis in HNSC, aimed at identifying reliable and HNSC-specific regions for cfDNA biomarker discovery. Traditional DMR analyses often overlook paired-sample information and fail to account for the heterogeneity within HNSC tissues. Our findings reveal a substantial overlap of hypermethylated DMRs across two independent HNSC methylation datasets, demonstrating the robustness and clinical relevance of these regions for cfDNA biomarker development. Furthermore, we identified consistent DMRs in both HNSC and lung squamous cell carcinoma (LSCC), suggesting the potential for pan-squamous cell carcinoma biomarkers. Notably, gene clusters such as
