Table 3.

15-year cumulative Risk (%) for all-cause and IHD mortality under natural course and “never exposed”, “exposed through 8 first years of follow-up” and “always exposed”, interventions, along with marginal Risk Ratios (RR, 95% CI), from the CFT model for the exposure Long-Haul Driver.

Natural Course	16.75	1.09 (1.05 –1.12)	5.46	1.09 (1.02 – 1.16)
Never Exposed	15.47	.	5.05	.
8-year exposure	18.97	1.23 (1.12 – 1.36)	6.08	1.20 (1.04 – 1.46)
Always Exposed	25.39	1.64 (1.34 – 2.06)	8.03	1.59 (1.12 – 2.47)
