NGT = Normal glucose tolerance; IFG = Impaired fasting glucose; IGT = Impaired glucose tolerance; T2D = Type 2 Diabetes; BMI = Body mass Index. ^aReference group = NGT subjects who remain NGT at follow-up; ^bReference group = IFG/IGT subjects who remain IFG/IGT at baseline. N_{NGT to IFG/IGT} = 972; n_{NGT to T2D} = 167; n_{IFG/IGT to T2D} = 1104. Linear regression analysis was performed.
