Fig. 2

Scatterplots of individual horse data (n = 60) showing the relationship between fasting indices for β-cell response: FI, fasting insulin concentration (a); MIRG, modified insulin-to-glucose ratio (b) and HOMA-β, homeostatic model assessment of β-cell function (c) versus the whole body glucose disposal rate (M index) as well as the relationship between proxies for insulin sensitivity: 1/insulin (d); RISQI, reciprocal of the square root of insulin (e) and QUICKI, quantitative insulin sensitivity check index (f) versus M index. The line in ac represents the regression line for log transformed data (Ln (y) = constant + β \(\times\) Ln (x)), whereas the line in df represents the regression line for weighted linear regression. Orange squares represent warmblood horses, blue triangles represent Icelandic horses whereas green circles represent pony breeds
