Multiple mediation of the impact of pictorial warning exposure on pictorial warning policy support at end of trial (week 4) (n=2,149)

Mediator variable	a pathway		b pathway		Mediated effect
Mediator variable	β_a	p	β_b	p	β_a* β_b (95% CI)	p
Perceived effectiveness of the warning	.36	<.001	.24	<.001	.09 (.07, .11)	<.001

Note. Table reports standardized path coefficients and mediated effects. a pathways are the associations between pictorial warning exposure and the mediators. b pathways are the associations between the mediators and policy support, controlling for pictorial warning exposure and the other mediators.
