Thirty students participated in the study, randomly assigned to either a teledidactic group or a face-to-face group. Despite randomization, the teledidactic group included more advanced students, with a higher proportion in their fourth and fifth years. The OSAUS final exam results were comparable between the two cohorts across all modules (p>0.05).

Fig 3: The performance of the final OSAUS exam for both the teledidactic (online) and face-to-face groups is presented. In each module, a maximum score of 35 could be achieved. The whiskers indicate the range within 1.5 times the interquartile range from the lower and upper quartiles. The boxes represent the interquartile range, with the lower and upper edges indicating the first and third quartiles, respectively. The line within each box denotes the median, providing a concise summary of central tendency. The modules include FAST (Focused Assessment with Sonography for Trauma) (A), lung (B), kidney and urinary tract (C), aorta and vena cava (D), and thyroid gland (E).

However, differences emerged in the assessment of images in the focused assessment with sonography for trauma (FAST) (p = 0.015) and aorta (p = 0.017) modules. Students in the teledidactic group performed higher than their face-to-face counterparts in both modules, scoring 33.59 (± 2.61) out of 44 in the FAST module (compared to 30.95 (± 1.76) in the face-to-face group), while aortic images averaged 35.41 (± 2.61) points versus 32.35 (± 3.08) points in the face-to-face group.
