  1. ǂPearson Chi-square test, P = 0.0001.
  2. *Represents a statistically significant difference within the paired groups (Pearson Chi-square test). LR OL, low risk oral leukoplakia; HR OL, high risk oral leukoplakia; OCSCC N + , oral cavity squamous cell carcinoma with cervical lymph node metastasis.
