    • Definition
      • a graphical representation of the diagnostic ability of different tests
      • used to determine responsiveness
    • Variables
      • False positive rate (1 - specificity)
        • is plotted on the x-axis
      • True positive rate (sensitivity)
        • is plotted on the y-axis
    • Interpretation
      • Area under the ROC curve (C-statistic)
        • used to compare different tests, higher C-statistics mean better diagnostic ability of test
          • an area under the ROC curve of 0.5 is a useless test
  • Survivorship Analysis
  • Minimal Clinically Important Difference (MCID)
  • Repeated Measurement Reliability
