Figure 3. No significant difference in antibody class switching between NR and active rejection cohorts was observed. (A, B) Levels of IgM and IgG1-4 in NR (n =30) and rejection (n = 35) groups. (C, D) Levels of IgM and IgG1-4 in NR (n =30), TCMR (n = 28), and ABMR (n = 7) cohorts. The dash dot line represents the mean value. The difference among the three subgroups was analyzed using one-way ANOVA. *P < 0.05. ABMR, antibody-mediated rejection; ANOVA, analysis of variance; NR, non-rejection; TCMR, T cell-mediated rejection.
