Diversity of parvalbumin-specific IgE levels varies in
demographic groups but not as a function of symptom severity, age or
gender
To investigate whether the diversity of IgE responses to different PVs
depends on clinical or demographic characteristics, Shannon’s diversity
index was calculated for each patient based on four categories of the
IgE levels to 10 parvalbumins (<0.3 kUA/L, 0.3-3.5 kUA/L,
3.5-13 kUA/L, >13 kUA/L). The diversity of the PV-sIgE
levels in serum did not depend on symptom score (Figure 2A ),
age group (Figure 2B ) or sex (Figure 2C ). A
significantly higher diversity of IgE levels to different PVs was
observed for the Chinese cohort than for the Austrian, Spanish or
Norwegian cohorts (Figure 2D ).
