a

Six subjects in the euglycaemia protocol and4 subjects in the acute hyperglycaemia protocol had plasma insulin levels below the limits of detection.

b

Within-protocol P-values reflect the point estimate for the mean pre- to post-intervention change in plasma insulin after conversion to the geometric mean ratio scale.

c

Between-protocol P-values represent the baseline-corrected ratio of geometric means (RGM) between protocols (i.e. RGM acute hyperglycaemia: RGM euglycaemia). AH, acute hyperglycaemia; CV, coefficient of variation; EU, euglycaemia; GM, geometric mean; ICAM-1, intercellular adhesion molecule-1.
