Clinical, histopathological, and molecular features of adrenal adenoma, IGF2-low carcinoma, and IGF2-high carcinoma.

These various characteristics were determined as detailed in Material and Methods. P-values were calculated with the Fisher's exact test (a) or Wilcoxon test (b) and show no significant differences between IGF2-high and IGF2-low ACC. When numbers do not add up to 10 for IGF2-low and 43 for IGF2-high, this indicates that data are not available for all patients.
