Participants’ subjective rating of their experience in performing intubation with versus without aerosol box

	Without aerosol box N=36	With aerosol box N=36	P value*
As intubator, no. (%)
Handling—easy and very easy	30 (83.3%)	25 (69.4%)	0.267
Visibility—good and very good	29 (80.6%)	21 (58.3%)	0.021
Confidence—confident and very confident	31 (86.1%)	25 (69.4%)	0.074
Movement—little and no limitation	31 (86.1%)	14 (38.9%)	<0.001
Perception of exposure risk—high and very high	25 (69.4%)	5 (13.9%)	<0.001
As assistant, no. (%)
Handling—easy and very easy	32 (88.9%)	28 (77.8%)	0.219
Visibility—good and very good	30 (83.3%)	22 (61.1%)	0.008
Confidence—confident and very confident	31 (86.1%)	27 (75.0%)	0.289
Movement—little and no limitation	29 (80.6%)	16 (44.4%)	0.002
Perception of exposure risk—high and very high	25 (69.4%)	2 (5.6%)	<0.001

Five-point Likert scale rating: handling of equipment (very difficult to very easy), visibility during performing the procedure (very poor to very good), confidence in achieving successful intubation (not confident to very confident), degree of movement (very limited to no limitation) and perception of risk of exposure to contamination (very low to very high).
