Average plasma insulin concentrations on day 4 before (baseline) and after hyperinsulinemic hypoglycemic clamp

Experimental Groups	RS	RH	RC	CRH
Baseline	3.2 ± 0.85	4.01 ± 0.98	4.36 ± 1.25	3.52 ± 1.06
Hypoglycemia	1,932 ± 120	2,230 ± 252	2,021 ± 323	2,032 ± 312

Values are means ± SE and in uIU/ml; data are summarized from 3 independent experiments (n ≥ 6/group). Experimental groups are as follows: RS, recurrent saline; RH, recurrent hypoglycemia; RC, recurrent cytisine; CRH, recurrent hypoglycemia + cytisine.
