Table 2

Age, duration of diabetes, and age at diagnosis of diabetic patients and control subjects.

	T2D ()	Ab^−T2D ()	Ab^+T2D ()	LADA ()	Controls ()
Age (y)	53.83 (6.76)	53.76 (6.66)	54.46 (7.86)	50.07 (7.86)	52.34 (4.17)
Age at diagnosis (y)	49.51 (7.53)	49.37 (7.42)	50.69 (8.68)	45.88 (8.44)	—
Diabetes duration (y)	4.36 (3.14)	4.43 (3.21)	3.77 (2.39)	3.27 (2.51)	—

Results are expressed as mean (standard deviation); n: number; T2D: type 2 diabetes; LADA: latent autoimmune diabetes of the adults; Ab-T2D: autoantibody-negative cases in T2D group; Ab⁺T2D: autoantibody-positive cases in T2D group; compared with control group only.
