In contrast, BIC and OST assessment using conventional cut-off values classified all horses as IS. Kappa coefficients, measuring agreement among BIC, OST, CGIT, and FSIGTT were poor to fair. Sensitivity of the CGIT (positive phase duration of the glucose curve &amp;gt;45 minutes) was 85.7% and specificity was 40%, whereas CGIT ([insulin]45 &amp;gt;100 \u03bcIU\/mL) sensitivity and specificity were 28.5% and 100%, respectively. Area under the glucose curve (AUCg0-120) was significantly correlated among the OST, CGIT, and FSIGTT, but Bland\u2013Altman method and Lin's concordance coefficient showed a lack of agreement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Current criteria for diagnosis of insulin resistance using BIC and the OST are highly specific but lack sensitivity.
