Also, we cannot fully exclude the possibility of false-negative results whenanalyzing associations between the UCP2 polymorphisms and DKD.Although we had more than an 80% power (α = 0.05) to detect an OR = 2.0 for theassociation with the -866G/A and Ins/Del polymorphisms, we cannot rule out thepossibility that these polymorphisms would be individually associated with DKD withlower ORs. The gene discussed is UCP2; the disease is diabetic kidney disease.
