Abbreviations: TTR, time to remission; PFS, progression-free survival; OS, overall survival; CI, confidence interval; FOXP3+ (% CD5+CD4+), frequency of FOXP3+ cells within the sequential CD5+ and CD4+ gates; FOXP3+ (%), frequency of FOXP3+ cells within the total harvested population; median ratio =  ratio of median remission or survival time (TTR/PFS/OS) of the sub-group of dogs with a value of the variable greater than the median of the group to that of the sub-group of dogs with a value of the variable less than or equal to the median of the group.
