Therefore, we experimentally expanded the sample population by adding those with diabetes without its medication and those with serum PRL levels between 25 and 50 ng/ml (namely, 3 with serum PRL levels over 50 ng/mL, 32 on medication for diabetes, and 20 with a fasting blood glucose level below 63 mg/dL or over 140 mg/dL, to better evaluate HOMA indices, were excluded from the original sample set of 441)(n = 386). The gene discussed is PRL; the disease is diabetes mellitus.
