  1. V MIN and V MAX : the minimal and maximal balloon volume representing the optimal filling volume with the least influence of balloon recoil pressure, V WORK : the difference between VMIN and VMAX, V BEST the best balloon filling volume
  2. Data are shown as median (interquartile range) [range]
