^*The Cox proportional hazards model was used to assess the effect of food group or soy protein consumption on the incidence of type 2 DM. RR: Adjusted for age, , daily energy intake, meat intake, BMI, WHR, smoking, alcohol consumption, physical activity, income level, education level, occupational status, and hypertension
