Two experiments were conducted on 19 October 2019 and 2 November 2019, respectively, and 10 resident physicians were enrolled for each experiment, for a total of 20 resident physicians. On 19 October 2019 and 2 November 2019, participating resident physicians were randomly assigned to two groups. In the medical interviews of simulated patients performed by the 20 resident physicians, the accuracy of the differential diagnosis, the time required for interviews, and the number of questions asked were evaluated. In the first test, one resident was unable to interview two cases with artificial intelligence-based assistance and five cases without artificial intelligence-based assistance. Therefore, in the first test, the results of 48 differential diagnoses with artificial intelligence-based assistance and 45 differential diagnoses without artificial intelligence-based assistance were obtained from interviews with 10 simulated patients (The correct diagnosis rates with and without information from the artificial intelligence-based support system for the two groups are shown in There was a significant difference in the rate of correct diagnosis between the two groups for two cases (case 7, 7/9 = 0.778 vs. 1/10 = 0.1, Comparisons of the time required and the number of questions with and without information from the artificial intelligence-based support system are shown in There was a significant difference in the time required between the two groups for overall cases (370 (352–387) seconds vs. 390 (373–406) seconds,
