结局指标

主要结局

Change From Baseline in Time-averaged Pain Intensity Visual Analog Scale (VAS) Score

时间窗: Time-averaged from the first available observation to the last available observation (12 months for completed subjects)

Visual analog scale (VAS) for pain (100mm line with "0/No pain" on the left and "100/Worst pain imaginable" on the right). Subjects drew vertical line to indicate pain. Time-averaged method accounts for time between visits by dividing area beneath the score curve by time between first and last available visits.

次要结局

  • Total Expenditure Per Day on All Lower Back Pain Related Interventions(Baseline, Month 01, Month 02, Month 04, Month 06, Month 08, Month 10, Month 12)
