Figure 2. Distribution of the frequencies of the possible combinations of only two KIR activating genes in the presence of their HLA Class I ligands in patients with and without ocular toxoplasmosis and its manifestations as primary or recurrent.

* and ** represents respectively that patients with recurrent manifestations and patients without ocular toxoplasmosis presented results of 0% for two activating pairs. ^aOR = 5.56; CI = 2.22–13.88; P = 0.0001; Pc = 0.0004 (Patients without ocular toxoplasmosis vs. Patients with ocular toxoplasmosis); ^bOR = 5.35; CI = 2.09–13.68; P = 0.0002; Pc = 0.0008 (Patients without ocular toxoplasmosis vs. Patients with primary manifestations); ^cOR = 6.50; CI = 1.92–21.96; P = 0.004; Pc = 0.01 (Patients without ocular toxoplasmosis vs. Patients with recurrent manifestations).
