Results of the generalised linear mixed model

Characteristic	Estimate (SE)	OR (95% CI)	P value
HBAI20 vaccine	1.25 (0.65)	3.48 (1.19 to ∞)	.028
Age (≥40 years)	−0.88 (0.73)	0.42 (0.10‐1.76)	.231
Male sex	−0.47 (0.64)	0.62 (0.18‐2.19)	.459
More than 1 hepatitis B vaccination cycle	−1.60 (0.82)	0.20 (0.04‐1.03)	.054

Age, sex and hepatitis B vaccination history were included as fixed effects in the model, in addition to vaccine allocation, ie, treatment effect. Trial site was included as a random effect.
