Change in the sum of dnDSA titer
The sum of dnDSA also decreased at 3 and 12 months after treatment in the IVIG + and IVIG − groups (Fig. Generalized estimating equation analysis for comparing the treatment effect of IVIG/rituximab with that of rituximab alone on class II dnDSA sum.
Visit was treated as a categorical variable. The MFI values were log-transformed. β refers to the coefficient estimated from the multivariate generalized estimating equation model. The β coefficients of the group × time interaction terms represent the difference in mean changes in MFI values at each time point with respect to the baseline between the IVIG + and IVIG − groups (mean change in IVIG + group − mean change in IVIG − group).
