This workshop was planned to teach the importance of clinical decision analysis and the ROC curve in clinical medicine. A pre-workshop test and post-workshop test were given before and after the workshop. In the clinical decision analysis a heart disease case was shown, a decision tree was made, and the chance node and expected value were calculated. The ROC curve was prepared from the results of urine analysis of patients with renal and urinary tract infections, and the cut-off points were changed variously. There were 27 participants. Twelve of them took both the pre-workshop test and post-workshop test, and about half of them answered that they understood how to perform the analysis. There tended to be more participants who understood how to make the clinical decision analysis than the ROC curve.
