Note: HPI = History of presenting illness; A/P/I = assessment/plan/intervention; *= no maximum number of promptings; SPE-1 = first simulated patient encounter; SPE-2 = second simulated patient encounter; CI = confidence interval; LL = lower limit; UL = upper limit. The 95% CI is reported for the difference between the means.
