Analysis of the calibrated automated thrombogram (CAT) and plasma-thromboelastography (plasma-TEG) between clinically healthy, mild gastrointestinal (GI) and severe GI disease horse groups. Median and range for plasma-TEG and thrombin generation parameters lag-time, time to peak (ttPeak), peak and endogenous thrombin potential (ETP). P-value column: one-way ANOVA or a Kruskal-Wallis test depending on normality of data across all three groups with a significance level of < 0.05. a Post hoc statistical significant difference between healthy and severe GI disease, b Post hoc statistical significant difference between mild and severe GI disease. SP: split point, R: reaction time, K: clot formation time, α: alpha angle, MA: maximum amplitude, G: shear elastic force, LY30: lysis 30 min, LY60: lysis 60 min (min.)
