SECONDARY outcome

Timeframe: 8 hours post single dose

Population: Number of participants analyzed includes only the number of participants with meaningful pain relief on Day 1 (see previous outcome measure #4). Number of patients in the placebo group is intentionally blank as the data (eg., median and upper CI) were not calculable (see post-hoc outcome measure #12 for available placebo results).

SECONDARY outcome

Timeframe: 8 hourse post single dose

Pain relief was rated using a 5-point categorial scale (0=none, 1=a little, 2=some, 3=a lot, and 4=complete) at time of dose (time=0) and over 15 time points afterwards (10, 15, 20, 30, 45, and 60 minutes and at 1.5, 2, 2.5, 3, 4, 5, 6, 7, and 8 hours after the initial dose on Day 1 or until time of re-medication). A score of 0 across all time points would be the lowest (worst) and a score of 60 (4 X 15 time points) would be the highest (best) possible score.
