主要结局
Sum of Pain Intensity Differences Over 24 Hours After Initiating Treatment (SPID 24)
时间窗: 24 hours
The primary efficacy outcome was the time-weighted SPID 24 (POW). Sum of pain intensity differences over 24 hours after initiating treatment (SPID 24) for the ITT population. SPID 24 derived from spontaneous Pain Intensity scores assessed over 24 hours on a 0 (No pain) - 10 (Pain as bad as you can imagine) Numerical Rating Scale. SPID 24 was computed using the trapezoidal rule, i.e. Σ \[T(i) - T(i-1)\] x \[((PID)(i-1) + PID(i))/2\] in an obvious notation, where T(i) is nominal time and PID(i), the pain intensity difference at Time i, is the baseline pain intensity (PI) score - PI score at Time i. Scores were assessed hourly for the first 4 hours and then every 2 hours whilst subjects were awake. Linear interpolation was used to compute an exact SPID as of 24 hours. SPID-24 was computed after all imputation of missing assessments and post-rescue assessments had been completed.
