Results obtained on CaBD and CNTN1 levels revealed clear cutoff values that allowed for subject classification based on infection status: All Pk-infected patients (19/19 [100%]) presented with plasma CaBD levels <1400 pg/mL or CNTN1 levels <12 500 pg/mL, whereas concentrations in all uninfected controls (19/19 [100%]) were >1400 pg/mL for CNTN1 and >15 000 pg/mL for CNTN1, respectively (Figure 2, Supplementary Results, Supplementary Table 5). The gene discussed is CNTN1; the disease is infection.
