*Costs compared using linear GEE model with gamma distribution and log link, clustered on recruit class.
All other outcomes (injury and claims frequency) compared using Poisson GEE model, clustered on recruit class.
(eβ1—1)×100=13% reduction in claims costs, comparing intervention group to controls.
GEE, generalised estimated equations; RA, recruit academy.
