The differences in the rs3024490 (<i>p</i> = 0.033) and rs1800871 (<i>p</i> = 0.033) allele frequencies of <i>IL-10</i> were determined between CP patients and controls.
IL-10 polymorphisms and protein association analysis showed that the TT genotype had higher plasma IL-10 protein levels compared to the GG + GT genotype at rs3024490 (11.14 ± 7.27 vs. 7.44 ± 6.95 pg/ml, <i>p</i> = 0.045, respectively) in CP cases.
