Figure 5.

Average speed attained. Similar to the data in Figure 4, a striking increase in speed was achieved by the 2-hour delayed PEG administration at 24 hours and 1 week post-injury (P ≤ 0.01); and by the 4-hour delayed PEG administration at day 4 post-injury. The 4-hour delay improved this outcome measure at 7 days post-injury, but the increase was not statistically significant. The 6-hour delay failed to produce any improvement. Note that these data were especially tightly grouped, and SEMs were not drawn onto the bar graph as they were too close to the mean to be easily discerned.
