Cerebral blood flow index (CBFi) relationship with outcome. CBFi (in units of 10−5 mm2/s) measured at baseline (A) and 4 hours after the third closed head injury (CHI) (B) in a five-hit daily repetitive CHI (rCHI) model versus average hidden trial latency across five hidden trials for sham (closed circles) and rCHI mice (open circles). The dotted and solid lines are trend lines computed from linear models for rCHI and sham mice, respectively.
