Usefulness of information presented in HC booklet	0.22 (0.07 to 0.37)*	0.20 (0.04 to 0.35)*	0.19 (0.04 to 0.35)*
Time between feedback and recall session (days)	−0.03 (−0.05 to −0.004)*		−0.02 (−0.04 to 0.01)
Feedback condition	0.48 (0.05 to 0.92)*		0.28 (−0.18 to 0.73)

β Estimates refer to the difference in total recall weighted score (from possible of 12.5) explained by each predictor of interest.

Multivariate model 1 estimates are adjusted for time between feedback and recall interview and feedback condition.

Multivariate model 2 estimates are adjusted for all other variables in the model.

*p<0.05.
