Effect of thymoglobulin on B lymphocyte subpopulations in pre- and post-transplant. The figure shows the relative frequencies of the BL subpopulations in RTR administered thymoglobulin (Blue bars, n = 12) and did not receive induction therapy (Black bars, n = 19). The values show mean ± SEM. The comparison within each group between pre-transplant and post-transplant values was performed using the Wilcoxon test for related samples. The comparison at each time between the group without induction and the thymoglobulin group was carried out using the Mann–Whitney U test. Values of p < 0.05 were considered statistically significant. * p < 0.05; ** p < 0.01.
