Figure 1:

CONSORT diagram for a study of the effects of resident duty schedules in the intensive care unit (ICU). On the basis of the study design, we anticipated evaluating outcomes from 980 admissions for 5505 patient-days, 74 sleepiness and 13 symptom measurements per resident, 288 continuity results and 960 ICU staff survey responses. Two residents participated in the schedule but did not consent to providing data for analysis. The n values for the Maslach Burnout Inventory represent number of measurements.
