Primary Outcome Measures:
  • The Time-Weighted Summed Pain Intensity Difference Measured Using the 100-mm Visual Analogue Scale From 0 to 48 Hours After Trial Entry (VASSPID-48), ANCOVA Model. [ Time Frame: 0 - 48 hours ] [ Designated as safety issue: No ]

    The pain intensity is assessed using a visual analogue scale (VAS), which is a horizontal line 100 mm in length. Subjects mark the VAS with a single vertical line to indicate their current pain level, with 0 mm representing "No Pain" and 100 mm representing "Worst Possible Pain".

    The VAS summed pain intensity difference (VASSPID) is calculated as the sum of the pain intensity difference values at each follow-up time point (difference between the starting pain intensity and the pain intensity at the given assessment time) multiplied by the amount of time (in hours) since the prior assessment.



Secondary Outcome Measures:
  • VASSPID-4. The Time-Weighted Summed Pain Intensity Difference Measured Using the 100-mm Visual Analogue Scale (VASSPID) From 0 to 4 Hours After Trial Entry. [ Time Frame: 0 - 4 hours ] [ Designated as safety issue: No ]

    The pain intensity is assessed using a visual analogue scale (VAS), which is a horizontal line 100 mm in length. Subjects mark the VAS with a single vertical line to indicate their current pain level, with 0 mm representing "No Pain" and 100 mm representing "Worst Possible Pain".

    The VAS summed pain intensity difference (VASSPID) is calculated as the sum of the pain intensity difference values at each follow-up time point (difference between the starting pain intensity and the pain intensity at the given assessment time) multiplied by the amount of time (in hours) since the prior assessment.


  • VASSPID-8. The Time-Weighted Summed Pain Intensity Difference Measured Using the 100-mm Visual Analogue Scale (VASSPID) From 0 to 8 Hours After Trial Entry. [ Time Frame: 0 - 8 hours ] [ Designated as safety issue: No ]

    The pain intensity is assessed using a visual analogue scale (VAS), which is a horizontal line 100 mm in length. Subjects mark the VAS with a single vertical line to indicate their current pain level, with 0 mm representing "No Pain" and 100 mm representing "Worst Possible Pain".

    The VAS summed pain intensity difference (VASSPID) is calculated as the sum of the pain intensity difference values at each follow-up time point (difference between the starting pain intensity and the pain intensity at the given assessment time) multiplied by the amount of time (in hours) since the prior assessment.


  • VASSPID-24. The Time-Weighted Summed Pain Intensity Difference Measured Using the 100-mm Visual Analogue Scale (VASSPID) From 0 to 24 Hours After Trial Entry. [ Time Frame: 0 - 24 hours ] [ Designated as safety issue: No ]

    The pain intensity is assessed using a visual analogue scale (VAS), which is a horizontal line 100 mm in length. Subjects mark the VAS with a single vertical line to indicate their current pain level, with 0 mm representing "No Pain" and 100 mm representing "Worst Possible Pain".

    The VAS summed pain intensity difference (VASSPID) is calculated as the sum of the pain intensity difference values at each follow-up time point (difference between the starting pain intensity and the pain intensity at the given assessment time) multiplied by the amount of time (in hours) since the prior assessment.


  • Total Pain Relief (TOTPAR) Over 0 to 4 Hours. TOTPAR-4. [ Time Frame: 0 - 4 hours ] [ Designated as safety issue: No ]

    Pain relief was assessed using a 5-point categorical scale at all assessment time points after time 0. Subjects were asked "How much relief have you had since your starting pain?" with response choices of none = 0, a little = 1, some = 2, a lot = 3, and complete = 4.

    The Total Pain Relief (TOTPAR) score for a given time interval is calculated as the sum of the pain relief scores at each follow-up time point (as recorded on the categorical pain relief scale) over that interval multiplied by the amount of time (in hours) since the prior assessment. In this way individual scores covering a longer time period were given more weight.The minimum theoretical score is 0 units, which represent no relief from pain (score of 0 on categorical scale) at all time points after time 0. The maximum theoretical score is 16 units, which represents complete relief from pain (score of 4 on a categorical scale) at all time points after time 0.


  • TOTPAR-8. Total Pain Relief (TOTPAR) Over 0 to 8 Hours [ Time Frame: 0 - 8 hours ] [ Designated as safety issue: No ]

    Pain relief was assessed using a 5-point categorical scale at all assessment time points after time 0. Subjects were asked "How much relief have you had since your starting pain?" with response choices of none = 0, a little = 1, some = 2, a lot = 3, and complete = 4.

    The Total Pain Relief (TOTPAR) score for a given time interval is calculated as the sum of the pain relief scores at each follow-up time point (as recorded on the categorical pain relief scale) over that interval multiplied by the amount of time (in hours) since the prior assessment. In this way individual scores covering a longer time period were given more weight. The minimum theoretical score is 0 units, which represent no relief from pain (score of 0 on categorical scale) at all time points after time 0. The maximum theoretical score is 32 units, which represents complete relief from pain (score of 4 on a categorical scale) at all time points after time 0.


  • TOTPAR-24. Total Pain Relief (TOTPAR) Over 0 to 24 Hours [ Time Frame: 0 - 24 hours ] [ Designated as safety issue: No ]

    Pain relief was assessed using a 5-point categorical scale at all assessment time points after time 0. Subjects were asked "How much relief have you had since your starting pain?" with response choices of none = 0, a little = 1, some = 2, a lot = 3, and complete = 4.

    The Total Pain Relief (TOTPAR) score for a given time interval is calculated as the sum of the pain relief scores at each follow-up time point (as recorded on the categorical pain relief scale) over that interval multiplied by the amount of time (in hours) since the prior assessment. In this way individual scores covering a longer time period were given more weight. The minimum theoretical score is 0 units, which represent no relief from pain (score of 0 on categorical scale) at all time points after time 0. The maximum theoretical score is 96 units, which represents complete relief from pain (score of 4 on a categorical scale) at all time points after time 0.


  • TOTPAR-48. Total Pain Relief (TOTPAR) Over 0 to 48 Hours [ Time Frame: 0 - 48 hours ] [ Designated as safety issue: No ]

    Pain relief was assessed using a 5-point categorical scale at all assessment time points after time 0. Subjects were asked "How much relief have you had since your starting pain?" with response choices of none = 0, a little = 1, some = 2, a lot = 3, and complete = 4.

    The Total Pain Relief (TOTPAR) score for a given time interval is calculated as the sum of the pain relief scores at each follow-up time point (as recorded on the categorical pain relief scale) over that interval multiplied by the amount of time (in hours) since the prior assessment. In this way individual scores covering a longer time period were given more weight. The minimum theoretical score is 0 units, which represent no relief from pain (score of 0 on categorical scale) at all time points after time 0. The maximum theoretical score is 192 units, which represents complete relief from pain (score of 4 on a categorical scale) at all time points after time 0.
