  1. Spousal traumatic brain injury was not clearly linked with major adverse cardiovascular events in humans (2740 married pairs; compared with no spousal traumatic brain injury) (HR 1.15, 95% CI 0.84–1.57).

Death risk was higher, with a hazard ratio—a measure of relative risk over time—of 1.24 compared with partners whose spouse had no traumatic brain injury.Death risk was higher, with a hazard ratio—a measure of relative risk over time—of 1.24 compared with partners whose spouse had no traumatic brain injury.
