  1. Values from Ins0 and Ins63 derived from base-10 logarithmic transformations
  2. ref reference values, ß coefficient, Ins0 basal insulin concentration prior to glucose injection, InsMAX maximum increase in blood insulin concentration, Ins63 insulin concentrations at 63 min, InsAUC insulin area under the curve, N noise, FS food stimuli, ns no statistically significant difference, not shown because values were not statistically significant, ref referent category
  3. aInsMax was estimated based on n = 107
  4. bInsAUC was estimated based on n = 106
