Mean value of lymphocyte subsets counts with standard deviations for 4 time points in group II. All subsets at 1 week post-treatment were significantly lower than at pretreatment. TLC, CD4⁺, and CD19⁺ at 4 weeks post-treatment were still lower than those at pretreatment, though nearly all subsets counts at 4 weeks post-treatment were higher than at 1 week post-treatment. Pre: pretreatment; Post: post-treatment; 1 w: 1 week post-treatment; 4 w: 4 weeks post-treatment.
