Out of the 41 inflammatory mediators investigated, only seven of them (IP-10; p = 0.045, VEGF; p = 0.049, IL-6; 0.049, IL-17A; p = < 0.0001, FGF-2; p = 0.025, MDC; p = 0.019, and GRO; p = 0.035) were found to be significantly elevated in the LC group when compared with the RC group, and only one cytokine (IL-3; p = 0.036) was found to be significantly reduced in the LC group when compared with HC group, as depicted in Table 4. This evidence concerns the gene CXCL1 and laryngotracheoesophageal cleft.
