Supplemental Figure S1 demonstrates the tumor-free survival when the lymphoma mice were removed. Tumor-free survival, when the lymphoma mice were removed, between the CD4-depleted mice treated with SQV + DMBA (10/15) and the CD4-depleted DMBA-treated mice (13/17) changed to non-significant (p-value = 0.0644). The gene discussed is CD4; the disease is neoplasm.
