The CKD prevalences were 11.4% and 17.8% for the IL4 CC and TT genotype carriers (OR = 0.59, 95% CI = 0.37-0.95, P = 0.029 after adjustment), and 11.6% and 16.3% for the IL6 GG and CC genotype carriers (OR = 0.67, 95% CI = 0.50-0.90, P = 0.008 after adjustment), respectively. Here, IL4 is linked to chronic kidney disease.
