Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time-Weighted Sum of Pain Relief Rating and Pain Intensity Difference Scores From 0 to 8 Hours (SPRID 0-8)	SPRID4:Time-weighted sum of pain relief rating (PRR) and pain intensity difference (PID) based on 4 point categorical severity rating scale (PRID) over 8 hours.SPRID 0-8 score range:-8 (worst score) to 56 (best score).PRID: sum of PRR and PID at each time point.PRID score range:-1= worst score to 7= best score.PID4 was calculated by subtracting the pain intensity score at given post-dose time points (pain severity score range: 0 [none] to 3 [severe]) from the baseline pain intensity scores (score range: 2 =moderate pain to 3 = severe pain; as participants with baseline pain score of at least moderate were included in study). Total possible score range for PID: -1 (worst score) to 3 (best score).PRR assessed on 5-point categorical scale with range:0 =no relief to 4 =complete relief.	From 0 hour up to 8 hours post-dose
Secondary	Time to Onset of Meaningful Pain Relief	Participants evaluated time to meaningful relief by stopping a second stopwatch labelled as "meaningful relief" at the moment they first began to experience meaningful relief. Stopwatch was active up to 12 hours after dosing or until stopped by participant, or participant became treatment failure prior to depressing the second stopwatch. Treatment failure was defined as participant taking rescue medication, or discontinuing due to lack of efficacy.	From 0 hour up to 12 hours post-dose
Secondary	Time to Confirmed First Perceptible Relief	Participants evaluated the time to first perceptible relief (confirmed by meaningful relief) by stopping the first stopwatch labelled 'first perceptible relief' at the moment they first began to experience any pain relief, if the participant also achieved meaningful relief by the end of the study. Stopwatch was active up to 12 hours after dosing or until stopped by the participant, or until the participant dropped out due to treatment failure (defined as participant taking rescue medication, or discontinuing due to lack of efficacy) prior to depressing the first stopwatch or until the time of withdrawal (discontinuation).	From 0 hour up to 12 hours post-dose
Secondary	Pain Relief Rating Score (PRR)	Participants answered a question: "how much relief do you have from your starting pain? on a 5-point categorical pain relief rating scale. Scale ranges from 0= no relief to 4= complete relief.	0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose
Secondary	Pain Intensity Difference on 4-Point Categorical Scale (PID4)	PID4: baseline pain severity score minus pain severity score at a given time point. Pain intensity was assessed on a 4-point categorical pain severity rating scale. PID4 was calculated by subtracting the pain intensity score at given post-dose time points (pain severity score range: 0 [no pain] to 3 [worst possible pain]) from the baseline pain intensity scores (score range: 2 =moderate pain to 3 =worst possible pain; as participants with baseline pain score of at least moderate were included in study). Total possible score range for PID4: -1 (worst score) to 3 (best score).	0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose
Secondary	Pain Intensity Difference on 11-Point Numerical Scale (PID11)	PID11: baseline pain severity score minus pain severity score at a given time point. Pain intensity was assessed on an 11-point numerical pain severity rating scale. PID11 was calculated by subtracting the pain intensity score at given post-dose time points (pain severity score range: 0 =no pain to 10 =worst possible pain) from the baseline pain intensity scores (score range: 5 =moderate pain to 10 =worst possible pain; as participants with baseline pain score of at least moderate were included in study). Total possible score range for PID11: -5 (worst score) to 10 (best score).	0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose
Secondary	Sum of Pain Relief Rating and Pain Intensity Difference on 4-Point Categorical Scale (PRID4)	PRID4: sum of PID and PRR at each post-dose time points up to 12 hours. Score range for PRID: -1(worst score) to 7(best score). PID was calculated by subtracting the pain intensity score at given post-dose time points (pain severity score range: 0 [no pain] to 3 [worst possible pain]) from the baseline pain intensity scores (score range: 2 =moderate pain to 3 =worst possible pain; as participants with baseline pain score of at least moderate were included in study). Total possible score range for PID4: -1 (worst score) to 3 (best score). PRR was assessed on a 5-point categorical pain relief rating scale which ranges from 0 =no relief to 4 =complete relief.	0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose
Secondary	Time-weighted Sum of Pain Intensity Difference on 4-Point Categorical Scale (SPID4) Over 2, 6, 8 and 12 Hours Post-Dose	Pain intensity was assessed on a 4-point categorical pain severity rating scale.

SPID4 score range was -2 (worst score) to 6 (best score) for SPID 0-2, -6 (worst score) to 18 (best score) for SPID 0-6, -8 (worst score) to 24 (best score) for SPID 0-8, -12 (worst score) to 36 (best score) for SPID 0-12. PID was calculated by subtracting the pain intensity score at given post-dose time points (pain severity score range: 0 [none] to 3 [severe]) from the baseline pain intensity scores (score range: 2 =moderate pain to 3 = severe pain; as participants with baseline pain score of at least moderate were included in study).

Secondary	Time-weighted Sum of Pain Intensity Difference on 11-Point Numerical Scale (SPID11) Over 2, 6, 8 and 12 Hours Post-Dose	Pain intensity was assessed on an 11-point numerical pain severity rating scale. SPID11: Time-weighted sum of PID scores over 12 hours. SPID11 score range was -10 (worst score) to 20 (best score) for SPID 0-2, -30 (worst score) to 60 (best score) for SPID 0-6, -40 (worst score) to 80 (best score) for SPID 0-8, -60 (worst score) to 120 (best score) for SPID 0-12. PID was calculated by subtracting the pain intensity score at given post-dose time points (pain severity score range: 0 =no pain to 10 =worst possible pain) from the baseline pain intensity scores (score range: 5 =moderate pain to 10 =worst possible pain; as participants with baseline pain score of at least moderate were included in study).
