  1. Pre-op before operation, Pro-op after operation
  2. * Values of this line are presented as mean (standard deviation), and the statistical method is the paired t test because the data are normally distributed
  3. ** Values of this line are presented as median (quartile range), and the statistical method is the rank-sum test because the data are not normally distributed. CVs, characteristic values
