  1. HW ratio: height to width ratio on the view vertical to the proximal stenosis vessel; Above the PV: the route starts at a suprapulmonic level and courses above the pulmonary valve; Below the PV: the route starts at a parapulmonic or subpulmonic level and courses below the pulmonic valve
  2. * The difference was tested by Student-t test
  3. ** The difference was tested by Wilcox test for the obvious outlies found on the Q-Q plot
  4. † The P value is for testing the difference of severity among three type of vessel routes
