Tested item	SBS	AC	AKC	VKC
Serum total IgE (IU/mL)	136±96.3	40.0±45.2**	5,340±5,757**	2,630±3,690**
Peripheral blood eosinophil count (%)	2.85±1.77	3.33±1.95	7.69±3.12#	7.77±3.40#
Number of MAST-positive antigens	1.08±0.90	1.42±0.85	5.57±1.70	3.95±1.96

Notes: Values are mean ± standard deviation. Serum total IgE was analyzed by independent t-test. Other items were evaluated by the Mann–Whitney U test.
