Length worked in trade versus ≤5 years
<1 year	3.50 (1.54, 7.95)	4.75 (1.33, 16.95)
2–5 years	2.43 (1.18, 4.50)	1.85 (0.63, 5.42)
Percent apprentice, per 10% increase	1.13 (1.02, 1.24)	1.27 (1.08, 1.49)
Number of tasks performed	NS	1.52 (1.16, 1.98)
Safer crew behaviors score	0.91 (0.86, 0.96)	0.91 (0.83, 0.99)

^*Excludes those who fell from a surface other than a ladder

All variables/scales were entered into the multiple logistic regression models, only significant variables/scales are reported.
