It has been suggested that the quality of clinical trials should be assessed by blinded raters to limit the risk of introducing bias into meta-analyses and systematic reviews, and into the peer-review process. There is very little evidence in the literature to substantiate this. This study describes the development of an instrument to assess the quality of(More)
UNLABELLED A consensus meeting was convened by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) to provide recommendations for interpreting clinical importance of treatment outcomes in clinical trials of the efficacy and effectiveness of chronic pain treatments. A group of 40 participants from universities,(More)
New studies of the treatment of neuropathic pain have increased the need for an updated review of randomized, double-blind, placebo-controlled trials to support an evidence based algorithm to treat neuropathic pain conditions. Available studies were identified using a MEDLINE and EMBASE search. One hundred and five studies were included. Numbers needed to(More)
OBJECTIVE To quantify the antiemetic efficacy and adverse effects of cannabis used for sickness induced by chemotherapy. DESIGN Systematic review. DATA SOURCES Systematic search (Medline, Embase, Cochrane library, bibliographies), any language, to August 2000. STUDIES 30 randomised comparisons of cannabis with placebo or antiemetics from which(More)
BACKGROUND Antiepileptic drugs have been used in pain management since the 1960s. Pregabalin is a recently developed antiepileptic drug also used in management of chronic neuropathic pain conditions. OBJECTIVES To assess analgesic efficacy and associated adverse events of pregabalin in acute and chronic pain. SEARCH STRATEGY We searched MEDLINE, EMBASE,(More)
An expert working group of the European Association for Palliative Care has revised and updated its guidelines on the use of morphine in the management of cancer pain. The revised recommendations presented here give guidance on the use of morphine and the alternative strong opioid analgesics which have been introduced in many parts of the world in recent(More)
Opioids are used increasingly for chronic non-cancer pain. Controversy exists about their effectiveness and safety with long-term use. We analysed available randomised, placebo-controlled trials of WHO step 3 opioids for efficacy and safety in chronic non-cancer pain. The Oxford Pain Relief Database (1950-1994) and Medline, EMBASE and the Cochrane Library(More)
OBJECTIVE To review the effectiveness and safety of topical non-steroidal anti-inflammatory drugs in acute and chronic pain conditions. DESIGN Quantitative systematic review of randomised controlled trials. DATA SOURCES 86 trials involving 10,160 patients. MAIN OUTCOME MEASURES Measures of treatment success approximating at least 50% reduction in(More)
One way to ensure adequate sensitivity for analgesic trials is to test the intervention on patients who have established pain of moderate to severe intensity. The usual criterion is at least moderate pain on a categorical pain intensity scale. When visual analogue scales (VAS) are the only pain measure in trials we need to know what point on a VAS(More)
Variability in patients' response to interventions in pain and other clinical settings is large. Many explanations such as trial methods, environment or culture have been proposed, but this paper sets out to show that the main cause of the variability may be random chance, and that if trials are small their estimate of magnitude of effect may be incorrect,(More)
