  1. PR the partial response group; SD the stable disease group; Pre-TBF pre-treatment tumor blood flow; Post-TBF post-treatment tumor blood flow; ΔTBF changes in tumor blood flow; AUC area under the curve; CI confidence interval
  2. athe PR group and the SD group
  3. bthe residual and non-residual tumors
