DREAM: an adaptive, randomised, placebo-controlled trial of duloxetine for reducing leg pain in people with chronic sciatica-trial protocol.

Introduction: Sciatica is a debilitating condition that often becomes chronic, and for which there are few effective treatment options. Treatments such as the anti-depressant duloxetine have shown promise, but the evidence is inconclusive. We are describing a high quality, definitive trial to investigate the efficacy, safety and cost-effectiveness of duloxetine in chronic sciatica.

The efficacy and safety of paracetamol for pain relief: an overview of systematic reviews.

Objective: To evaluate the efficacy and safety of paracetamol as an analgesic medication in a range of painful conditions.

Study Design: Systematic review of systematic reviews of the analgesic effects of paracetamol in randomised, placebo-controlled trials. Conduct of systematic reviews was assessed with AMSTAR-2; confidence in effect estimates (quality of evidence) was assessed with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria.
