Post, post-intervention period; Pre, pre-intervention period. Pre-intervention period: 1 January 2000–31 December 2003; post-intervention period: 1 January 2004–31 December 2006.
↵* p<0.05.
↵† Time trends in the pre (Pre(%)) and post (Post(%)) intervention periods are expressed as the mean percentage increase/decrease in the number of people injured per month, statistically significant trends being indicated with an asterisk (*). Relative change is expressed as the mean percentage increase/decrease in the number of people injured per month in the post-intervention period compared with that in the pre-intervention period.
