What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time-Weighted Sum of Pain Relief Rating and Pain Intensity Difference Scores From 0 to 8 Hours (SPRID 0-8)
Time Frame: From 0 hour up to 8 hours post-dose
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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

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