In what approximated a controlled clinical trial for efficacy of seatbelts, the Colorado matched pairs study examined 256 crashes meeting the following criteria: driver plus front-seat passenger, one belted (SB) and one nonbelted (NSB) occupant, and at least one occupant injured.
Nearly half (119 of 256) of the SB partners escaped injury, while only 16% (41 of 256) of the NSB group were as fortunate.
To ascertain a differential effect the 160 pairs discordant for injury were analyzed.
The relative odds for injury in the SB group was 0.34 (95% CI:0.24, 0.49) of that in the NSB group.
Likewise, relative odds for any medical costs in the SB group was reduced to 0.24 (95% CI:0.14, 0.43) and for hospitalization to 0.29 (95% CI:0.10, 0.80).
