Table 4. Adjusted analysis of work surface contamination rate by protective method and variables of interest.

Variables	Odds ratio (95% confidence interval)	P value
Protective method (BladePouch vs. single or double gloves†)	0.0054 (0.0009–0.0314)	<0.001
Intubation device (video laryngoscope vs. direct laryngoscope)	1.82 (0.51–6.53)	0.353
Professional role of participant		0.393
Allied health professional vs. trainee	2.39 (0.44–13.11)
Attending physician vs. trainee	7.13 (0.30–170.93)
Number of previous intubations		0.079
16–30 vs. ≤15	9.28 (1.07–80.34)
>30 vs. ≤15	0.67 (0.07–6.50)

^†, since all (40/40) single gloves protective method trials resulted in work surface contamination, the single and double gloves protective methods were combined in the modeling of the work surface contamination outcome.
