FIGURE 2.

Accuracy of DMI indices in development phase in training cohort and blind-test phase on both Chinese and German test cohorts. Results in cross-validation were plotted using receiver-operating-characteristic curves. Results in Chinese blind-test cohort were illustrated as single points, where overall represents results of all tested 330 patients. One hundred eight patients in blind test underwent follow-up scanning, and performance of these at baseline and follow-up was plotted. Blind-test results in German cohort (90 patients) are also included and denoted with black rectangle for easy comparison.
