Groups2
Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Pregabalin | Pregabalin 75 milligram (mg) capsule administered by mouth (PO) twice daily (BID) for 7 days. On Day 8, dose may have been maintained at 150 mg per day or increased to 300 mg per day. Each week thereafter, including at Visit 4, a dose increase or decrease may have occurred depending on clinical judgement on adequate pain relief and tolerability. Following the end of adjustment phase, at Visit 4, participants were at their optimized dose (150 mg per day, 300 mg per day, 450 mg per day, or 600 mg per day). Participants remained at this maintenance dose throughout the next 12 weeks of the study. | 48 | 100 | OG000 |
