Generalisability of the observed effect sizes for the interaction between policy scenario and tobacco user type in Freitas-Lemos et al ¹⁹ and the current study

	Freitas-Lemos et al	England	Canada	USA
Vaping ban×dual users	1.93	96.97	3583.03	441.15
Total flavour vaping ban×dual users	1.37	70.87	3071.94	339.2
Partial flavour vaping ban×dual users	—	78.74	985.03	293.03
Vaping ban×e-cigarette users	256.2	5226.26	10 073.88	64 035.49
Total flavour vaping ban×e-cigarette users	33.52	1360.38	1871.09	1194.56
Partial flavour vaping ban×e-cigarette users	—	226.42	541.43	422.25

Effect sizes are reported as ORs with the reference group being the purchasing pattern of cigarette smokers in the no ban scenario. Results from Freitas-Lemos et al are repeated here for convenience. Note the partial flavoured vaping ban scenario was not considered in Freitas-Lemos et al.
