Structural path coefficients, indirect and total effect for the mediation model.

Path			b	CI Lower	CI Upper	SE	β
D-score NEG	→	Vaccination	0.05	−0.06	0.19	0.07	0.05
D-score POS	→	Vaccination	0.21 **	0.06	0.35	0.07	0.20
D-score NEG	→	Explicit prop.	0.72 **	0.21	1.21	0.26	0.24
D-score POS	→	Explicit prop.	−0.21	−0.80	0.44	0.32	−0.06
Explicit prop.	→	Vaccination	0.09 **	0.05	0.15	0.03	0.29
Indirect effect of D-score POS			0.07 *	0.02	0.15	0.03	0.07
Indirect effect of D-score NEG			−0.02	−0.09	0.03	0.03	−0.02
Total effect			0.31 **	0.09	0.50	0.11	0.30

Note. b = unstandardized coefficient, CI lower and CI upper = lower and upper 95% bootstrapped confidence intervals of b, SE = standard error, β = standardized coefficient. D-score POS = D-scores for VACCINE-positive trials; D-score NEG = D-scores for VACCINE-negative trials. The significant level is indicated as follows: * p < 0.05, ** p < 0.01.
