The methodology was interesting, worth a read. Participants were given a
complex inpatient case presentation, and instructed to use a "think aloud"
protocol. Judgement of correct dx was by an expert panel.

differences were not statistically significant. Participants who took longer
to complete the case scenario were more accurate.
