HOMA-IR, fasting glucose, as well as glucose 30, 60, 90 and 120 minutes after oral glucose load higher vs controls; fasting insulin insignificantly higher vs controls; impaired fasting glucose in 34% of patients, impaired glucose tolerance in 19% of patients, insulin resistance in 34% of patients; glucose at 30 and 90 minutes after glucose load higher in SV than SW. This evidence concerns the gene INS and Insulin resistance.
