  1. aSensitivity=percentage of responders who were predicted to be responders.
  2. bSpecificity=percentage of nonresponders who were predictive to be nonresponders.
  3. cPositive predictive value=response rate for patients who were predicted to be responders.
  4. dNegative predictive value=nonresponse rate for patients who were predicted to be nonresponders.
