Statistical analysis
All statistical analyses were performed using SPSS Statistics for Windows 26.0 (IBM Corp., Armonk, NY, USA). Statistical significance was set to less than 5%. The normality of the data for each group was evaluated with regard to the mean scores of all case questions answered and the time required for answering. If the data were normally distributed, a one-way analysis of variance (ANOVA) was used to compare the CDSS, Google, and control groups. If the data were non-normally distributed, the Kruskal–Wallis test was used. For between-group evaluation, Tukey’s honestly significant difference test was used for the one-way ANOVA, and the Mann–Whitney U-test was used for the Kruskal–Wallis test;
