Table 3.

Adjusted Odds Ratios and 95% Confidence Intervals for being involved in a Crash for the Seven Groups of Cardiovascular Disease Risks.

Framingham 10-Year CVD Risk	N (%)	Number or drivers reporting having been in a DOT crash (%)	Odds Ratio	95% Confidence Intervals
Lowest Risk (0%)	123 (15.4)	36 (29.3)	1.00	(Reference)
1-2%	149 (18.7)	47 (31.5)	1.14	0.67	1.94
3-5%	107 (13.4)	43 (40.2)	1.58	0.90	2.78
6-8%	108 (13.6)	41 (38.0)	1.30	0.73	2.29
9-12%	120 (15.1)	48 (40.0)	1.45	0.83	2.54
13-20%	122 (15.3)	60 (49.2)	2.06*	1.18	3.60
Highest Risk (21-30%)	68 (8.5)	33 (48.5)	2.00*	1.05	3.77

^*p<0.05 adjusted for gender, body mass index and cell phone use while driving in the city. There was a significant trend in increased risk for crash across the CVD risk groups (p= 0.0046).
