G2.5: glucose 2.5 mmol/L; G5: glucose 5.0 mmol/L; G20: glucose 20 mmol/L. Data are mean ± SEM. Paired comparisons were obtained by changing one experimental variable at a time. Negative values indicate a higher IL-1β (a) and IL-10 (b) concentration in the latter condition considered. ^∗p < 0.05, ^∗∗p < 0.01. Student's t-test for paired data indicating a significant change between the paired experimental conditions stated in the first column.
