However, gender (P = .810), aspartate transaminase (P = .053), age (P = .261), alcoholism (P = .315), alpha‐fetoprotein (P = .673), alanine transaminase (ALT) (P = .426), tumor scale (P = .350), portal vein invasion (P = .658), and TNM stage (P = .088) were not correlated with the expression of TUG1. Here, AFP is linked to alcohol dependence.
