  1. #The joint index is the combination of superficial vessel density, deep vessel density, superficial perfusion density, and deep perfusion density
  2. $There is no cut-off for joint index
  3. AUC area under the receiver operating characteristic curve, CI confifidence interval
  4. *P value compared with null hypothesis: true area = 0.5
