*4.7. Statistical Analyses*

IBM SPSS statistics v. 24 was used for the statistical analysis. Data were expressed as mean ± standard deviation or median [25◦–75◦]. Differences between variables were evaluated using one-way ANOVA followed by Bonferroni's or Dunnett's post-hoc tests, when appropriate, and paired (to compare the expression between the adrenal nodule and the corresponding adjacent adrenal cortex) or unpaired *t*-tests or Mann–Whitney tests. A probability of less than 0.05 was considered as statistically significant.
