  • Genotypes were encoded as 0 = the presence of the G-308G genotype of the TNF-α gene and the −174G allele of the IL-6 gene and 1 = the presence of the −308A allele of the TNF-α gene and the C-174C genotype of the IL-6 gene. Weight change was calculated as (weight [kg] 3 years − weight [kg] baseline)/weight (kg) baseline × 100%. If diabetes was diagnosed before the 3-year examination, the weight at the visit when diabetes was diagnosed was used in statistical analyses.
