Emergence time for month in residency. Median (interquartile range) emergence time (a) and incidence (95% confidence interval) of prolonged emergence (b) by month in anesthesia residency training for 27 residents. Dashed lines represent least squares linear regression fit. Fit model for emergence time (months 1–12): Pearson rr² = 0.51, P < 0.01, Y-intercept = 8.8 min, slope = –0.21 min/month. Fit model for prolonged emergence incidence (months 1-12): Pearson r² = 0.65, P < 0.01, Y-intercept = 18.7%, slope = –0.8%/month
