Survival rates of animals with canine mammary carcinoma. Kaplan-Meier survival curves for animals for All (MC-BMT and MC) animals categorized according to the relative percentage of CD4⁺ T-cells (<66.7% or ≥ 66.7%) and CD8⁺ T-cells (≤ 33.3% or >33.3%) (A). Animals were submitted to quarterly follow-ups during twelve months and survival rates expressed in days between the surgical excisions of the end of follow-up as described in Methods. The survival curves were estimated with the Kaplan-Meier method followed by Log-rank test. Correlation analysis highlighted the significant association between the percentages of CD4⁺ T-cells and CD8+ T-cells with the animal survival in days (B).
