Association of common laboratory tests with disease activity in EGPA in multivariable regression models after adjusting for repeated measures and treatment status

Predictor variable	Prevalence risk ratio (95% CI)	P-value
Absolute eosinophil count	1.01 (1.01, 1.02)	<0.01
IgE	1.02 (0.99, 1.02)	0.31
ESR	1.15 (1.04, 1.27)	<0.01
CRP	0.98 (0.73, 1.03)	0.90

Risk ratios are reported per 100 U increase for absolute eosinophil count and IgE and per 10 U increase for ESR and CRP. EGPA: eosinophilic granulomatosis with polyangiitis.
