Frequencies of seropositive and seronegative samples for anti-T. gondii antibodies in the analyzed groups as determined by ELISA

	IgM				IgG
	Seropositive		Seronegative		Seropositive		Seronegative
	n	%	n	%	n	%	n	%
G1 (n = 85)	0		85	100	37	43.5	48	56.5
G2 (n = 11)	0		11	100	2	18.1	9	81.9
G3 (n = 62)	2	3.2	60	96.8	31	50	31	50

G1 vs. G2 → p-value = 0.1904; OR = 3.47; 95% CI = 0.70–17.03

G1 vs. G3 → p-value = 0.5038; OR = 0.77; 95% CI = 0.40–1.49

G2 vs. G3 → p-value = 0.0972; OR = 0.22; 95% CI = 0.04–1.11

G1 sickle cell disease patients, G2 homozygous beta-thalassemia patients, G3 heterozygous beta-thalassemia minor patients
