  1. This table presents the relationships between microsatellite analysis, XCI pattern, and clinical parameters (including tumour grade, lymph node metastases, and tumour size).
  2. a. N: The XCI pattern in the tumour tissues was non-random.
  3. b. R: The XCI pattern in the tumour tissues was random.
  4. c. LNM+: Patients with lymph node metastases.
  5. d. LNM–: Patients without lymph node metastases.
  6. e. Chi-square test and Fisher’s exact probability test.
