Interestingly, subgroup analysis according to the ethnicity revealed that the IL10 rs1800896 polymorphism was significantly associated with reduced pediatric asthma risk in Asians (fixed‐effect model, OR = 0.311, 95% CI = 0.152–0.637, P = 0.001) but no significant association in Egyptians (random‐effects model, P = 0.395) (Figure 2B). The gene discussed is IL10; the disease is asthma.
