MFI variability is, on average, not affected by the IBM. (A and C) Swarm plots depicting the mean of the absolute MFI change, between consecutive SAB measurements, for five different IBM categories (in days), for (A) class 1 and (C) class 2 anti-HLA antibodies. The IBM category is denoted by differently colored dots. (B and D) Mean and SD of the mean absolute MFI change for the five IBM categories. Each group contains the same number of measurements: (B) n=253 for class 1 and (D) n=242 for class 2. After correcting for multiple hypothesis testing, no pair of time differences showed a statistically significant mean absolute MFI change.
