A linear regression analysis model (backward method) showed that Hsp72 (Beta = 0.32, p = 0.001) and IL-6 (Beta = 0.34, p = 0.008) were independently associated with TOS, whereas survivin protein (Beta = −0.22, p = 0.017) and Hsp72 (Beta = −0.24, p = 0.01) were inversely associated with TAC. This evidence concerns the gene BIRC5 and persistent truncus arteriosus.
