Comparison of positive rates of antibody to MT (Ab to MT) and antibody to hsp70 (Ab to hsp70)

	Ab to MT		Ab to hsp 70
Subjects	No. positive	(%)	No. positive	(%)
Group I (n = 78)	3	(3·8)	4	(5·1)
Group II (n = 78)	5	(6·4)	4	(5·1)
Group III (n = 39)	20	(51·3)*†	17	(43·6)*†

Group I, healthy controls; Group II, patients suffering from atopic dermatitis without metal allergy; Group III, patients suffering from atopic dermatitis with metal allergy.

^*P < 0·0001, compared with Group I, and

^†P < 0·0001, compared with Group II, significant differences on χ² and Fisher's exact test.
