INS and type 1 diabetes mellitus: Postprandial glucose-insulin dynamics were quantified using the single tracer oral minimal model, accounting for non-steady-state insulin exposure.<h4>Results</h4>At baseline, individuals with type 1 diabetes had significantly higher plasma glucose concentrations than control individuals (10.7±2.3 and 5.2±0.4 mmol/l, respectively; p<0.001), while preprandial glycogen levels did not differ significantly.
