TABLE 3

First- and second-phase insulin secretion and insulin sensitivity in subjects with normal fasting glucose (NFG), impaired fasting glucose (IFG), and type 2 diabetes, subdivided as in Tables 1 and 2, expressed as percentage of expected with adjustment for age, gender, BMI, and WHR. Multiple linear regression was performed on data of NFG/NGT subjects for the assessment of the adjustment for age, gender, BMI, and WHR.
