Table 4 Effects on first attempt success

	Crude model		Adjusted model
	Odds ratio (95% CI)	p-value	Odds ratio (95% CI)	p-value
Device (SensaScope vs Bonfils)	0.64 (0.45–0.92)	0.016	0.65 (0.46–0.93)	0.020
Trial	1.10 (1.04–1.16)	< 0.001	1.10 (1.04–1.16)	< 0.001
Mallampati (III/IV vs. I/II)			0.88 (0.47–1.63)	0.68
BMI (per unit increase)			0.97 (0.94–1.01)	0.15
Consultant vs. registrar			1.70 (1.00–2.88)	0.05
Intercept	2.44 (1.57–3.78)	< 0.001	3.67 (1.34–10.07)	0.011

Effects expressed as odds ratio with 95% confidence intervals (CI) from a crude model with device and trial number and an adjusted model with Mallampati score, BMI, and physician (consultant vs. registrar)
