Identification of Fractures on Still Ultrasound Images. An array of bar graphs depicting participant scores on a series of questionnaire items that asked participants to evaluate still ultrasound images of cadaveric bones for fracture. Participant scores were analyzed via a one-tailed T-test and then aggregated into bins spanning 10 percentage points. The Y axis of each panel represents the number of participant responses. Panels A-C display results of the pre-, post-, and 5-months post-training assessments respectively. The mean score of 77.4% rose to 91.7% following training (p = 0.001). Five months post-training, the average score fell slightly to 89.8% correct (p = 0.325)
