Indices of glucose metabolism calculated from the OGTT at 30–32 weeks revealed that PTX3 levels was positively associated with insulin sensitivity (r = 0.23, p < 0.001) and β-cell function (r = 0.18, p = 0.003), and negatively with insulin resistance (r = −0.23, p < 0.001). The gene discussed is INS; the disease is Insulin resistance.
