TNF-α and IL-6. Geometric mean plasma TNF-α (a) and geometric mean plasma IL-6 (c) measured at baseline and hourly after glucose ingestion, both with 95 % confidence intervals (CI). Geometric mean iAUC of plasma TNF-α (b) and geometric mean iAUC of plasma IL-6 (d) with 95 % CI. #Significant difference between groups. iAUC incremental area under the curve, IL interleukin, IVGI intravenous glucose infusion, OGTT oral glucose tolerance test, TNF tumour necrosis factor
