Stratified analysis revealed a significant reduction in FL pulse pressure difference in chronic\u2010phase patients (45.0\u2009\u00b1\u200920.9 to 28.9\u2009\u00b1\u200917.5,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.002). Additionally, 73.9% of patients had higher systolic pressure in TL with an earlier systolic peak, multivariable analysis identified more visceral arteries originating from FL (OR\u2009=\u20090.02, 95% CI\u2009=\u20090.01\u20130.47) and FL being closer to the spine (OR\u2009=\u20090.05, 95% CI\u2009=\u20090.01\u20130.77) as factors associated with higher FL systolic pressure.
