Abstract
Safety belt use was associated with a reduced risk of death for rear car occupants: outboard rear seat adjusted relative risk 0.42 (95% CI 0.38 to 0.46), and center rear seat adjusted relative risk 0.30 (95% CI 0.20 to 0.44). For rear occupants of light trucks, vans, and utility vehicles, the estimates were: outboard adjusted relative risk 0.25 (95% CI 0.21 to 0.29), center 0.34 (95% CI 0.24 to 0.48). If the authorsÆ estimates are causal, traffic crash mortality can be reduced for rear occupants by approximately 55û75% if they use safety belts. (Author/publisher).
