Figure 2. Percentage of Patients with Unplanned Intubation by the Unplanned Intubation Risk Index (UIRI) Score.

Figure 2

The percentage of patients who experienced unplanned intubation for each scoring category in the UIRI is shown for both the derivation and validation cohorts. T bars indicate standard error. *Scores 17 and 18 were combined because of the small numbers of unplanned intubation cases in the UIRI 18 group (2 in the derivation cohort and 1 in the validation cohort).
