Threshold effect analysis of TG on incident diabetes using piece-wise linear regression.

	Incident diabetes
	Crude model			Adjusted model I			Adjusted model II
	HR (95%CI)	P value		HR (95%CI)	P value		HR (95%CI)	P value
Per 10mg/dl increment
TG<53mg/dl	0.384 (0.227, 0.649)	0.0003		0.321 (0.186, 0.555)	< 0.0001		0.413 (0.220, 0.778)	0.0062
TG>53mg/dl	1.080 (1.046, 1.115)	< 0.0001		1.083 (1.048, 1.118)	< 0.0001		1.091 (1.046, 1.137)	< 0.0001

Crude model adjusted for none.

Adjusted model I adjusted for Age, BMI (body mass index, kg/m2), Waist circumference (cm); Body Weight (kg).

Adjusted model II adjusted for model I plus ethanol consumption (g/week); ALT, AST, regular exercise, GGT, HDL-cholesterol, Total Cholesterol, HbA1c, smoking, Fasting plasma glucose, systolic blood pressure, diastolic blood pressure, and father or mother with diabetes.
