Mixed meal test results (median (IQ range)) by 90 minute MMT stimulated C-peptide (SCP, nmol/L) tertile
Tertile 1 (SCP ≤ 0.02,n = 27) Tertile 2 (SCP 0.02-0.8, n = 27) Tertile 3 (SCP ≥ 0.8, n = 26) p for trend
Glucose increment in MMT (without insulin, mmol/L) 10.6 (9.0-13.7) 9.9 (8.2-11.0) 7.1 (4.4-8.9) 0.001
Glucose increment in MMT+I (insulin given, mmol/L) 4.3 (0.4-8.8) 4.4 (2.2-4.4) 5.2 (3.6-6.4) 0.45
Reduction in glucose increment when prandial insulin given (mmol/L): all participants (n = 80) 6.4 (4.2-11.1) 4.0 (2.5-7.9) 1.2 (0.03-2.88) 0.001
Reduction in glucose increment when prandial insulin given (mmol/L): Rapid analogue insulin only* (n = 61): 6.7 (4.3-11.2) 4.0 (2.3-7.9) 1.4 (1.8-3.0) 0.001
Reduction in glucose increment when prandial insulin given (mmol/L): Type 1 only (n = 54) 6.9 (4.2-11.3) 4.0 (2.4-7.8) 1.9 (0.3-3.5) 0.002
Reduction in glucose increment when prandial insulin given (mmol/L): Type 2 only (n = 26): 5.1 (4.2-6) 4.5 (2.4-9.2), 1.1 (−0.3-2.4) 0.006

Participants completing both MMT and MMTI only.
