Table 2 Intra-cluster correlation (ICC) of serum total IgE (sIgEtot) evaluated over the 12-month study period in three strata of asthmatic patients based on sIgEtot at baseline: < 76 IU/mL (n = 10); 76–700 IU/mL (n = 20) and > 700 IU/mL (n = 11)
From: Variability in total serum IgE over 1 year in severe asthmatics
ICC (95% CI) (*) | 1-ICC (95% CI) | p-value (**) | |
|---|---|---|---|
< 76 IU/mL | 96 (93–98) % | 4 (2–7) % | |
76–700 IU/mL | 71 (62–82) % | 29 (18–38) % | < 0.0001 |
> 700 IU/mL | 96 (94–99) % | 4 (1–6) % |
