Figure 4From: High Immune Response Rates and Decreased Frequencies of Regulatory T Cells in Metastatic Renal Cell Carcinoma Patients after Tumor Cell VaccinationSurvival probability of patients with high versus low frequencies of MDSC4. Survival probability of the patients (n = 12) with MDSC4 in %/lymphocytes < median (solid line) and MDSC4 in %/lymphocytes > median (dashed line). Median = 12.13%; p = 0.091; log-rank test.Back to article page
