Fig 3 Box-and-whisker plots and histograms of the cost of abdominal aortic aneurysm repair with open repair (OR) and endovascular repair (EVAR) using a population-based study8. (A) total, (B) preoperative, (C) perioperative, and (D) postoperative cost. In the box-and-whisker plots (left in each figure), the box indicates the interquartile range (IQR; left line is the lower quartile [Q1], middle line is the median, right line is the upper quartile [Q3]); the whiskers indicate the smallest and largest non-outlier observations within 1.5 IQR below Q1 or above Q3. The black circles (•) indicate mild outlier (1.5-3 IQR below Q1 or above Q3). The asterisk (*) shows an extreme outlier (>3 IQR below Q1 or above Q3). In the histograms (right in each figure) staples indicate the number of observations (N) in a specific cost interval. The full line indicates the mean; dashed lines indicate the 95% confidence interval. N, Number of observations in each interval.
