  1. a Number of cases.
  2. b Immunohistochemistry staining score expressed as mean ± SD.
  3. c P-value, ANOVA test of equal means among the four groups (* equal population variances assumption did not meet, corresponding p-value using Kruskal-Wallis test for equal medians was displayed).
  4. d Two-sided 95% confidence interval (C.I.) for the difference in means, Dunnett’s post-hoc test compared to value in healthy (in Diagnosis group) or clear cell (in Histology group) as the “reference” group. Dunnett’s test was performed only when the ANOVA or Kruskal-Wallis result was significant (p < 0.05).
  5. ** Significant based on Dunnett’s test (family error rate set to 0.05).
