[en] A software which performs the construction and the statistical comparison between ROC curves is proposed. It uses quantitative or qualitative (i.e. obtained by the rating method) data. The statistical test is based on a method proposed by J.A. Hanley which compares the values of the areas under the ROC curves and takes automatically into account the correlation between the data. The software runs on IBM PC compatible computers. It may be of great help for clinical studies
