CAN was measured as variability in the R-R interval during deep breathing, and PWA was performed using SphgymoCor Px (AtCor Medical, Sydney, Australia). Other clinical and demographic factors were also assessed. Univariate and multivariable analyses for associations with CAN were performed for arterial stiffness measures (augmentation index [AIx] and augmentation pressure [AP]) and a myocardial perfusion measure (subendocardial viability ratio [SEVR]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Presence of CAN was univariately associated with all three PWA measures: AIx (odds ratio [OR]=1.5,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =0.03), AP (OR=2.1,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =0.001), and SEVR (OR=0.4,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt;0.001).
