Plasma insulin concentrations were increased (P = 0.03) in all obese pigs combined (n = 20) by 28% (from 53±6 to 67±9 pmol/L) at increased (P = 0.04) plasma fructosamine x plasma insulin concentrations by 33%, a measure of insulin resistance (from 3152±420 to 4190±580 A.U.)and at increased (P = 0.03) blood glucose x plasma insulin concentrations by 22%, the HOMA-index of insulin resistance (from 36±4 to 44±4 A.U.). Here, INS is linked to Insulin resistance.
