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)0-48 hoursThe 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. Pain intensity is assessed at baseline (time 0) and at the following time points after time 0: 15, 30, and 45 minutes and 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 12, 16, 20, 24, 32, 40, and 48 hours. 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.

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. Pain relief is assessed at the following points after time 0: 15, 30 & 45 minutes and 1, 1.5, 2, 3 & 4 hours. 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. Thus, individual scores covering a longer period were given more weight. The minimum theoretical score is 0 units, which represents no pain relief (0 on scale) at all points after time 0.

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)

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. Pain intensity is assessed at baseline (time 0) and at the following time points after time 0: 15, 30, and 45 minutes and 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 12, 16, 20, 24, 32, 40, and 48 hours. 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.

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. Pain intensity is assessed at baseline (time 0) and at the following time points after time 0: 15, 30, and 45 minutes and 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 12, 16, 20, and 24 hours. The VAS summed pain intensity difference (VASSPID) is calculated as a time-weighted 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-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.

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. Pain intensity is assessed at baseline (time 0) and at the following time points after time 0: 15, 30, and 45 minutes and 1, 1.5, 2, 3, and 4 hours. 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.

Time frame: 0-4 hours

Population: Intent-to-Treat Population. All subjects who received at least 1 dose of trial drug.

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.

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. Pain intensity is assessed at baseline (time 0) and at the following time points after time 0: 15, 30, and 45 minutes and 1, 1.5, 2, 3, 4, 5, 6, 7, and 8 hours. 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.
