KDM5D and head and neck squamous cell carcinoma: Nevertheless, when KDM5D abundance was alternatively split at the lowest quartile, significance was retained for both head-neck squamous cell carcinoma (HR 1.75 [95% CI 1.3, 2.5], P = 0.0011) and liver hepatocellular carcinoma (HR 1.82 [95% CI 1.1, 2.9], P = 0.0099).
