Figure 2.

Illustration of the general linear model used to investigate the main and interaction effects with respect to the length of stay at baseline and follow-up after adjusting for the time of the day using physician-led team triage versus nurse triage. Physician-led team triage (blue bars, dark gray) during day-time at follow-up was compared with the same period at baseline. Nurse triage (green bars, light gray) during night-time at follow-up was compared with the same period at baseline (95% CI).
