Levels of polyclonal immunoglobulins by the three main patient M-protein subgroups in MIX and MXI. Statistics were performed for the three main patient groups with sufficient sample size (IgG, IgA and LCO). Significant differences between groups are indicated, ***p < 0.001. Dotted lines indicate the lower limit of the normal range of serum polyclonal immunoglobulin concentration: 6 g/L IgG, 0.8 g/L IgA and 0.5 g/L IgM
