Data of cohort I and the control group in double logarithmic immunoglobulin (Ig)M, IgA, and free light chain kappa (FLC-k) quotient diagrams. The first column includes data from cohort I with combined IgA and IgM synthesis (circles). All FLC-k quotients are above Qlim–FLC-k. Column 2 contains the data of patient samples with an isolated IgA synthesis (asterisks) or isolated IgM synthesis (triangles). Of the FLC-k quotients, 98% are above Qlim–FLC-k. Column 3 displays the data of the control group (circles), in which 7.9% of the FLC-k quotients are above Qlim–FLC-k. The bold line shows Qlim, the dashed line shows the Qmean. The bottom dashed line shows the Qlow. QLim/mean/low–IgG/IgA/IgM/FLC-k = upper/mean/lower limit of the hyperbolic reference range; IF = intrathecal fraction.
