Mean of 3 peak insulin values during first-phase insulin secretion in response to
glucose bolus (AIR-gluc), arginine bolus (AIR-arg), and glucose + arginine (GPAIS),
in 6 recent-onset KPD patients and 3 control participants. Values are means ± SEMs.
aSignificantly different from control group,
P < 0.05 (t test). AIR, acute insulin response;
GPAIS, glucose potentiation of arginine-induced insulin secretion; KPD,
ketosis-prone diabetes.
