Fig. 1Hourly major discrepancy rates for preliminary reports generated by radiology residents for three years. The major discrepancy rate increases with increasing consecutive working hours.
Fig. 2Major discrepancy rates for preliminary reports generated by radiology residents according to experience. Box-and-Whisker plots show no correlation between residents' experience and the major discrepancy rate. Each color plot represents the major discrepancy rate for each resident as experience in ER increases.
