Categorical data are given as numbers and percentages. Continuous data are given as mean value with standard deviation (for a normal distribution) and median value with interquartile range (25th–75th percentiles) (for a non-normal distribution). P values are calculated by Student’s t test, Mann–Whitney U test, χ2 test, or Fisher’s exact test, as appropriate.
ACEI/ARB = angiotensin-converting enzyme inhibitor/angiotensin receptor blockers, ASA = American Society of Anesthesiologists, BMI = body mass index, CCB = calcium channel blockers, IMH = intramural hematoma, LMWH = low-molecular-weight heparin, PAU = penetrating aortic ulcer, PCI = percutaneous coronary intervention.
