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.

AKI = acute kidney injury, TEVAR = thoracic endovascular aortic repair.
