Cumulative incidence of deaths in the hospital. The cumulative incidence of hospital death did not differ significantly between the two groups (220 in oversedation prevention group vs. 253 in the control group): hazard ratio for the oversedation prevention group versus the control group, 0.85; 95% confidence interval, 0.71–1.01; p = 0.06. For the analysis of time from randomization to death in the hospital, alive hospital discharge was handled as a competing risk
