Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (15)

  • Time to Onset of Meaningful Pain Relief

    From 0 hour up to 12 hours post-dose

  • Time to Confirmed First Perceptible Relief

    From 0 hour up to 12 hours post-dose

  • Pain Relief Rating Score (PRR)

    0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose

  • Pain Intensity Difference on 4-Point Categorical Scale (PID4)

    0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose

  • Pain Intensity Difference on 11-Point Numerical Scale (PID11)

    0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose
