Evaluating Receiver Operating Characteristic (ROC) analysis programs reveals that no single software offers adequate functionality. While Analyse-It, AccuROC, and MedCalc show promise, limitations persist, necessitating further program development.

Area of Science:

  • Medical Diagnostics
  • Biostatistics
  • Laboratory Medicine

Background:

  • Receiver Operating Characteristic (ROC) analysis is a standard for evaluating diagnostic test accuracy.
  • Numerous ROC analysis software programs have emerged recently without systematic evaluation.
  • Assessing the usability and correctness of these new ROC tools is crucial.

Purpose of the Study:

  • To evaluate eight Windows-based ROC programs for ease of use, mathematical accuracy, output quality, and compatibility.
  • To compare the performance of different ROC software in analyzing diagnostic test validity.

Main Methods:

  • Eight ROC programs (AccuROC, Analyse-It, CMDT, GraphROC, MedCalc, mROC, ROCKIT, SPSS) were assessed.
  • ROC analysis was performed on prostate-specific antigen data from 928 men.

  • Evaluation criteria included data input/output, result correctness, and completeness.

    • Main Results:

    • All programs yielded comparable areas under the curve, but data handling and output completeness varied.
    • Analyse-It, AccuROC, and MedCalc demonstrated good performance, yet each had specific drawbacks.
    • GraphROC uniquely allowed curve comparison at specific sensitivity or specificity thresholds.

    Conclusions:

    • No single ROC program provides complete analysis and plotting capabilities.
    • Analyse-It, AccuROC, and MedCalc are recommended with reservations.
    • Improvements in current ROC software are needed for comprehensive diagnostic accuracy assessment.
