  1. Spearman Correlation Coefficients.
  2. The Ki67 index for Patient Cohort #1 was based on the relative mRNA level. The Ki67 index for Patient Cohort #2 was based on Immunohistochemical analysis.
  3. § The expression levels of SOD2 for Patient Cohort #1 were based on the relative mRNA level. The expression levels of SOD2 for Patient Cohort #2 were generated from Immunohistochemical analysis.
  4. * p < 0.05. The p values were computed using Fisher's transformed z-score test.
