Outcomes

Primary Outcome Measures

the Sum of Pain Intensity Differences(SPID)
SPID is derived as the weighted Sum of Pain Intensity Differences (baseline pain - current pain), measured at different time points via the PI-VAS. Time between two consecutive measurements will be used for weighting. Larger values indicate larger pain relief.

Secondary Outcome Measures

the Sum of Pain Intensity Differences(SPID)
the Sum of Pain Intensity Differences(SPID)
Pain Intensity Differences(PID)
Include pain intensity differences(PIDs) from baseline at each time point. measured at different time points via the PI-VAS.
Pain relief(PAR)
pain relief (PAR) on a 5-point Likert scale (0, none, 1, a little, 2, some,3, a lot, 4, complete).
the Sum of Pain relief Differences(SPAR)
SPAR is derived as the weighted Sum of Pain relief, measured at different time points via the 5-point Likert scale. Time between two consecutive measurements will be used for weighting. Larger values indicate larger pain relief.
the Sum of Pain relief Differences(SPAR)
the Sum of Pain relief Differences(SPAR).
Subject who reaches a 30% reduction in pain intensity from baseline
Subject who reaches a 50% reduction in pain intensity from baseline
time to perceptible pain relief
time to meaningful pain relief
Patients used one stopwatch to record the time to 'perceptible' PAR and another stopwatch for the time to'meaningful' PAR.Patients started timing upon intake of study medication and stopped one stopwatch at the onset of perceptible PAR and another upon achieving meaningful PAR.
Time to first use of rescue medication
Proportion of subjects who take of at least 1 dose of rescue medication
Subject's overall assessment of study medication
Patients made an overall assessment of the study medication using a verbal rating scale (excellent, verygood, good, fair, poor).
