Table 2.

Summary statistics for secondary efficacy variables. On day 0, LOCF was applied. The treatment by time interaction was significant for all variables, therefore comparisons at each time (0.5, 1, 3, 5, and 8 hours) are reported. On days 1 and 2, data are provided without LOCF applied. Groups were not compared statistically after 8 hours.
