In the N-ERD vs. asthma comparison, PPARG-rs2960421, both SNPs of IL10, PTGER2-rs1409165, and OBSCN-rs4465344 showed an association p < 0.04, OR < 1 in the codominant model, only IL10-rs1554286CC and IL10-rs1800872CC persisting with the effect in the dominant model (p = 0.006, OR = 0.51/p < 0.02, OR = 0.56). Here, PTGER2 is linked to asthma.
