Performance scores 3 months before (pre-intervention) and 6 months after implementation of the intervention, and difference in performance between the feedback-only and feedback-with-toolbox group for the primary and secondary outcomes

	Feedback only			Feedback with toolbox

ORs associated with a 6-month increase in time; significant results are shown in bold.

*Pre-intervention performance includes 3 months before implementation of the intervention.

†Performance after 6 months includes months 3 to 6 after implementation of the intervention.

‡Significantly different from the feedback-only group with p=0.049.
