From: Plasma cfDNA VILL gene methylation as a diagnostic marker for nasopharyngeal carcinoma
Comparison of the diagnostic performance of VILL methylation and EBV DNA. A: All patients with nasopharyngeal carcinoma (NPC); B: Patients with early-stage nasopharyngeal carcinoma; C: Patients with advanced nasopharyngeal carcinoma. Chi-square test or fisher’s exact test was used to analyze statistical significance (**: P < 0.01; ***: P < 0.001; NC: no significance)
