Perceived improvement in physiological functions in e-cigarette-only users and dual users: binary logistic regression analyses

Variable	OR	[95%CI]	ORadjusteda	[95%CI]
Breathing	3.64	[2.35–5.63]	3.39	[2.15–5.33]
Smell	4.33	[2.95–6.35]	4.12	[2.77–6.12]
Taste	3.41	[2.36–4.94]	3.21	[2.18–4.72]
Physical status in general	3.36	[2.38–4.74]	2.28	[1.56–3.32]
Stamina	3.36	[2.38–4.74]	3.11	[2.17–4.45]
Mood	2.21	[1.58–3.08]	2.09	[1.48–2.96]
Quality of sleep	1.74	[1.24–2.43]	1.70	[1.21–2.41]
Appetite	1.58	[1.12–2.20]	1.57	[1.09–2.25]
Sexual performance	1.68	[1.17–2.43]	1.68	[1.14–2.48]
Memory	1.62	[1.09–2.40]	1.59	[1.06–2.40]

Note: Reference group is dual users. ^a: adjusted for age, gender, and duration of e-cigarette use. All ORs are significant at least at p < 0.050. Bolded ORs remained significant after Bonferroni correction for multiple testing. The adjusted level of significance after Bonferroni correction is p < 0.005
