Exp (estimate) provides the ratio of model-adjusted mean swim durations between TBI and Sham groups. The Hommel-adjusted p-values compensate for multiple testing. By the third swim of day 2, the TBI group had about double the latency of the Sham group, although this doesn't show significance until day 3. Bold = p < 0.05.
CI, confidence interval; SE, standard error; TBI, traumatic brain injury.
