Longitudinal models, with and without adjustment for population (n=202)
| Relative change in cycle KSI, 1991–2001 | Relative change in cycle KSI, 2001–2011 | |||
| Model A | Model B | Model A | Model B | |
| Relative change in cycle commuters | 0.33 (0.10 to 0.56) | 0.34 (0.11 to 0.57) | 0.79 (0.50 to 1.08) | 0.75 (0.42 to 1.08) |
| Relative change in motor vehicle kilometres | −1.14 (−2.35 to 0.08) | −1.16 (−2.39 to 0.07) | 2.15 (0.87 to 3.43) | 2.19 (0.89 to 3.49) |
| Relative change in population | −0.13 (−0.75 to 0.50) | 0.45 (−1.19 to 2.08) | ||
Model A implements equation 3a, model B implements equation 3b: the difference between the two is that model B additionally adjusts for the local authority population size.
KSI, killed or seriously injured.
