Relationship between perceived difficulty of quiz questions and ChatGPT's accuracy. The x-axis represents the percentages of correct choices made by the participants, grouped in quartiles, from most difficult (Q1) to easiest (Q4). The number of correct and total choices published on the New England Journal of Medicine Image Challenge website was used as a proxy for perceived difficulty. The y-axis represents the accuracy of ChatGPT's responses, both with choices (blue line) and without choices (green line). ChatGPT's accuracy remained consistent across the perceived difficulty quartiles of the quiz questions
