Comparison Between the Two Studied Groups According to the Percentage of Selective/Partial IgA Deficiency

Serum IgA	Total Patients		Group A (n = 20)		Group B (n = 20)		χ2	p
	No.	%	No.	%	No.	%
Normal	14	35.0	3	15.0	11	55.0	7.033*	0.008*
Low	26	65.0	17	85.0	9	45.0
Type of IgA Deficiency	Total Patients (n=26)		Group A (n=17)		Group B (n=9)		χ2	p
	No	%	No.	%	No.	%
Partial	10	38.5%	4	23.5%	6	66.7%	4.626	0.031
Complete	16	61.5%	13	76.5%	3	33.3%

Notes: p, p value for comparing between the studied groups; *Statistically significant at p ≤ 0.05; Group A, asthmatic patients with recurrent chest infections; Group B, asthmatic patients without recurrent chest infections; Group C, healthy controls.

Abbreviation: χ², chi square test.
