Clinical and biochemical subject characteristics with respect to type 2 diabetes mellitus.

Differences in categorical variables were tested for statistical significance with the Chi-square test. For continuous variables t-tests were applied. Non-normally distributed variables [i.e. age, BMI, HDL cholesterol, LDL cholesterol, triglycerides, fasting insulin, fasting glucose, homeostasis model assessment (HOMA) insulin resistance (IR), and HOMA beta cell function (BCF)] were log-transformed prior to statistical analysis. Continuous variables are given as mean ± SD (of non log-transformed values).
