Metabolic Profiling of Patients Undergoing Elective Aortic Aneurysm Repair Surgery: Correlation with Anaerobic Threshold
Figure 2
(a) PLS-DA plot (, , and ) for the postoperative samples normalised to the preoperative sample for each patient. Black triangles represent patients who scored lATs, and red squares represent hAT patients. The main solid black ellipse surrounding the majority of the scores in each plot is Hotelling’s T2 elliptical tolerance region, which indicates the 95% confidence limits. A clear separation can be seen between hAT and lAT preoperative scores. (b) The loadings plot reveals the chemical shift regions responsible for this separation.
