Forearm blood flow (FBF) at baseline and after all three doses of Ach or SNP.

	Lean controls	Overweight	Obese class I	Obese class II	Obese class III
FBF prior to Ach infusion	1.5±0.4	1.7±0.4	2.1±0.6	1.9±0.5	1.7±0.5
FBF after Ach infusion	10.9±2.9	9.4±3.0	6.6±1.5*	5.9±1.5*	3.7±1.1#
FBF prior to SNP infusion	1.6±0.6	1.9±0.2	2.1±0.7	1.8±0.7	2.0±0.7
FBF after SNP infusion	9.6±1.8	9.3±1.6	7.6±2.2*	6.7±1.9*	5.1±1.5#

Results are expressed as means ± SD for each group. FBF is expressed in mL.100 mL⁻¹ forearm volume.min⁻¹.
