Fig. 1From: Center effect in intubation risk in critically ill immunocompromised patients with acute hypoxemic respiratory failureCrude intubation rate by center (left) and distribution of center effects on intubation rate (right) adjusted on individual confounders. Centers are sorted by study size. Black squares represent adjusted center effects on the mean intubation risk as odds ratio (OR) (comparison of each center to a theoretical average reference center with OR = 1). a The TRIAL-OH cohort. b The HIGH trial.
