This graph illustrates the effect of the electronic decision support tool (eDST) on performance compared with native behavior for each question and overall. The eDST significantly improved overall performance and performance for each question, except for question 3 where the scoring for both eDST and control was more than 95% correct. The error bars for the overall mean show the SD for each group across the entire test. Data are shown as mean ± 95% CI.
