HRs (95% CI) of CVD and CHD for subjects with glucose intolerance at the first visit with their changing status at first follow-up. HR, hazard ratios; CI, confidence interval; CVD, cardiovascular disease; CHD, coronary heart disease; NFG normal fasting glucose; IFG, impaired fasting glucose; NGT, normal glucose tolerance; IGT, impaired glucose tolerance. NFG/NGT was defined as those with both NFG and NGT states. IFG/IGT was defined as those with IFG and/or IGT. Model 1: Age, sex. Model 2: Model 1 systolic blood pressure, diastolic blood pressure, total cholesterol, high density lipoprotein-cholesterol, waist circumference, eGFR physical activity, smoking, education and use of anti-hypertensive drug. Model 3: Model 2 + change of waist circumference, total cholesterol and high density lipoprotein-cholesterol. a Hazard of CVD in subjects with IFG at the first examination; b hazard of CVD in subjects with IGT at the first examination; c hazard of CVD in subjects with IFG/IGT at the first examination; d hazard of CHD in subjects with IFG at the first examination; e hazard of CHD in subjects with IGT at the first examination; f hazard of CHD in subjects with IFG/IGT at the first examination
