IGF1 and Hypoglycemia: Moreover, patients with a pre-operative serum IGF-1 concentration above the calculated median of the whole cohort of 111 ng/ml had a significantly higher risk of post-load hypoglycemia (OR 4.8; 95%CI: 1.15–20.1; p = 0.0275) while the median cut-off value for post-operative IGF-1 concentration was not significantly associated with a higher risk.
