To establish the IL-17A cutoff that would permit the identification of patients with IND and CARD forms of ChD, an analysis was performed that allows a division of the individuals into three categories: low (3.66–12.69 pg/mL), intermediate (12.88–24.88 pg/mL), and high (24.89–48.33 pg/mL) IL-17A producers. Here, IL17A is linked to coronary artery disorder.
