Fig. 2.
Box plots of IgG (n = 224; upper panel) and IgA (n = 82; lower panel) concentrations in myeloma patients separated by low (0 to 9 μg/L; left), intermediate (10 to 120 μg/L; middle), and high (>120 μg/L; right) HYA serum values (number of patients in each group is given in Table 1). The horizontal lines in the plots represent the 10th, 25th, 50th, 75th, and 90th percentile, respectively. The differences between the abnormally low and intermediate HYA value groups were significant (P = .016 [IgG] and P = .009 [IgA], respectively).
