Length of stay was associated with the severity of illness scores, the blood glucose, C-peptide levels, insulinemia (Table 3), the time from admission to the onset of hyperglycemia (r = 0.532, p = 0.002), the maximum dose of insulin (r = 0.539, p = 0.004), and the duration of treatment with insulin (r = 0.602, p = 0.001). This evidence concerns the gene INS and Hyperglycemia.
