  1. The association between resident duty hours and hospital type was analysed using a proportional odds regression model with GEE and robust variance estimation to account for hospital variability. We used community hospital residents as the reference for our analysis.
  2. N number, OR odds ratio, CI confidence interval.
  3. †Adjusted for academic year, age, sex, postgraduate year, number of ED duties per month, number of assigned inpatients, daily self-study time, hospital area, and number of annual ambulance arrivals. Residents who did not provide information on adjusted factors were excluded from multivariable analysis (256 participants).
