Regression analyses of differences in severity measures and mortality after implementation of the camera ticketing system among patients without road-traffic injuries (n=5778 patients).

Variables	Linear regression (ISS dependent variable)	Linear regression (GCS dependent variable)	Logistic regression (odds of mortality)
Pre-implementation	Reference	Reference	Reference
Post-implementation	−.08 (−0.65, 0.48)	0.00 (−0.12, 0.12)	0.80 (0.61, 1.0)

R-squared for ISS: 0.008, GCS: 0.007. Pseudo-R-squared for mortality model: 0.001
