  • *Tumor incidence was defined by the number of tumor-bearing rats divided by the total number of rats.

  • Both tumor incidence and total number of tumors presented in this table are histologically confirmed adenocarcinomas.

  • Multiplicity was defined by the total number of tumors divided by the total number of tumor-bearing rats.

  • §Tumor inhibition was calculated based on the total number of tumors.

  • P < 0.05.
