Graphic Narrative Versus Journal Article for Teaching Medical Students About P Values: A Randomized Trial

Abstract

BRIEF DESCRIPTION OF THE PROBLEMUnderstanding P values is difficult but essential for interpreting the medical literature. Graphic narratives (comics) facilitate scientific communication and may be an enjoyable way for learners to grasp difficult concepts [1], including the meaning of a P value. Previous studies have shown that comics improve student [2], patient [3], and resident [4] understanding of medical information and often outperform traditional instructional methods. Junhasavasdikul et al [2] found better third-year student results on a thoracostomy quiz in students randomized to a comic compared with a text-based handout. Brand et al [3] showed that patients having angiography given a comic explaining the procedure had better understanding and satisfaction and less anxiety than patients receiving only standard informed consent.We performed a randomized trial to compare knowledge level by exposure to a comic or a traditional journal article describing P values among firstyear medical students.
