		Correlation analysis sCD30*		Correlation analysis sCD26*
	Median value (range)	r	P	r	P
Serum IgE (U/ml)	4455 (20–57 900)	0·324	0·0351	0·277	0·0159
Serum LDH (U/l)	250 (136–648)	0·729	< 0·0001	0·508	< 0·0001
Eosinophil (/μl)	581 (131–4759)	0·714	< 0·0001	0·397	0·0003
Serum sCD25 (U/ml)	552 (249–3230)	0·879	< 0·0001	0·272	0·2114
Eruption area (%)	31 (2–89)	0·804	< 0·0001	0·419	< 0·0001
Eruption score	36 (4–77)	0·586	< 0·0001	0·277	0·0159

Reference values: serum IgE, < 380 U/ml; serum lactate dehydrogenase (LDH), 114–243 U/l; peripheral eosinophil counts, < 420/μl; serum sCD25, 246–742 U/ml.

^*The values except for eruption areas and eruption scores were log-transformed for linear regression analyses.
