Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Total Pain Relief Score Over the First 6 Hours (TOPAR6) After the Initial Dose	TOPAR6 was calculated by multiplying the pain relief (PR) score (0- to 4-point scale, with 0=None, and 4=Complete for pain relief) at each time point by the duration (in hours) since the preceding time point, and summing these weighted values up to 6 hours post the initial Day 1 dose. The range of TOPAR6 score is 0 to 24, with increasing scores indicating greater pain relief.	Baseline and 0.5, 1, 1.5, 2, 3, 4, 5 and 6 hours
Secondary	Sum of Pain Intensity Difference Scores Over the 6-Hour Time Period (SPID6)	The Pain Intensity Difference (PID) score is the difference between the baseline pain intensity (PI) score and the PI score recorded at each time point post initial dose, as calculated by subtracting the pain intensity at each of the subsequent time points from the baseline pain intensity score; therefore, it is on a -1 to 3 scale, with a large value representing a greater treatment effect. SPID6 is derived by multiplying the PID score at each time point by the duration (in hours) since the preceding time point, and summing these weighted values up to 6 hours and it is on a scale of -6 to 18.	Baseline and 0.5, 1, 1.5, 2, 3, 4, 5 and 6 hours
Secondary	Mean Participant Global Evaluation of Pain at 6 Hours After the Initial Dose (GLOBAL6)	The GLOBAL6 was recorded by the participant at 6 hours (or at the time of rescue medication use) after taking the first dose of study medication. The GLOBAL6 uses a pain relief scale of 0 to 4, where 0 = poor pain relief, 1 = fair pain relief, 2 = good pain relief, 3 = very good pain relief, and 4 = excellent pain relief.	6 hours
Secondary	Mean Participant Global Evaluation of Pain at 24 Hours After the Initial Dose (GLOBAL24)	The GLOBAL24 was recorded by the participant at 24 hours (or at the time of rescue medication use) after taking the first dose of study medication. The GLOBAL24 uses a pain relief scale of 0 to 4, where 0 = poor pain relief, 1 = fair pain relief, 2 = good pain relief, 3 = very good pain relief, and 4 = excellent pain relief.	24 hours
Secondary	Mean Time to >=1 Unit Improvement From Baseline in Pain Intensity During the 6 Hours After the Initial Dose	The time to a change from baseline in pain intensity score of >=1 unit on the pain intensity scale was calculated. The pain intensity scale rates participant pain on a scale of -1 to 3, with larger values associated with greater treatment effect.	Baseline and 6 hours
Secondary	Peak Pain Intensity Difference (PID) During the 6 Hours After the Initial Dose	Peak PID during the 6 hours post initial dose is defined as the maximum PID score recorded during first 6 hours after the initial dose of study medication. PID is evaluated on a scale of -1 to 3, with larger values representing a greater treatment effect.	Baseline and 0.5, 1, 1.5, 2, 3, 4, 5 and 6 hours
Secondary	Peak Pain Relief (Peak PR) During the 6 Hours After the Initial Dose	Peak PR during the 6 hours post initial dose is defined as the maximum PR score; recorded during the first 6 hours after the initial dose of study medication. PR is recorded on a scale of 0 to 4, with 0 = no pain relief, 1 = little pain relief, 2 = some pain relief, 3 = a lot of pain relief, and 4 = complete pain relief.	Up to 6 hours
Secondary	Number of Participants Using Rescue Medication 24 Hours After the Initial Dose	Acetaminophen 250 mg, isopropylantipyrine 150 mg and anhydrous caffeine 50 mg (Saridon) was provided to each participant as rescue medication. Participants were permitted to take 2 tablets at a time and up to 3 doses within 24 hours of dosing of study drug for rescue purposes.	24 Hours
Secondary	PID at Up to 12 Hours Following the Initial Dose	PID during the 12 hours following the initial dose is defined as the maximum PID score recorded during first 12 hours after the initial dose of study medication. PID is evaluated on a scale from 0 to 3, with 0 = no pain, 1 = slight pain, 2 = moderate pain, and 3 = severe pain.	Baseline and 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 and 12 hours
Secondary	PR at Up to 12 Hours Following the Initial Dose	PR during the 12 hours following the initial dose is defined as the maximum PR score recorded during the first 12 hours after the initial dose of study medication. PR is evaluated on a scale of 0 to 4, with 0 = no pain relief, 1= a little pain relief, 2 = some pain relief, 3 = a lot of pain relief, and 4 = complete pain relief.	Up to 12 hours
Secondary	PID at Up to 24 Hours Following the Initial Dose	PID during the 24 hours following the initial dose is defined as the maximum PID score recorded during first 24 hours after the initial dose of study medication. PID is evaluated on a scale from 0 to 3, with 0 = no pain, 1 = slight pain, 2 = moderate pain, and 3 = severe pain.	Baseline and 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 12, 20 and 24 hours
Secondary	PR at Up to 24 Hours Following the Initial Dose	PR during the 24 hours following the initial dose is defined as the maximum PR score recorded during the first 24 hours after the initial dose of study medication. PR is evaluated on a scale of 0 to 4, with 0 = no pain relief, 1= a little pain relief, 2 = some pain relief, 3 = a lot of pain relief, and 4 = complete pain relief.	Up to 24 hours
Secondary	Number of Participants With a Global Evaluation of Study Medication of Good, Very Good, or Excellent at 6 Hours After the Initial Dose	At 6 hours following the initial dose. participants were asked to rate their perception of pain control as poor, fair, good, very good, or excellent. The number of participants that reported good, very good, or excellent pain control at 6 hours post initial dose were summed.	6 hours
Secondary	Number of Participants With a Global Evaluation of Study Medication of Good, Very Good, or Excellent at 24 Hours After the Initial Dose	At 24 hours following the initial dose of study medication, participants were asked to rate their perception of pain control as poor, fair, good, very good, or excellent. The number of participants that reported good, very good, or excellent pain control at 24 hours post initial dose were summed.	24 Hours
