Medicines are the most common treatment for back pain. The aim of this program of research is to improve our understanding of the clinical effects of medicines.

Studies currently in progress:

  1. Scoping review of paracetamol, NSAIDs and opioid analgesics for chronic low back pain (led by Matthew K Bagg). The objective of this study is to identify and describe the characteristics of available clinical trials of commonly used analgesic medicines for chronic low back pain. This information will inform the design and conduct of other studies in the research program.
  2. Paracetamol, NSAIDs and opioid analgesics for chronic low back pain: a network meta-analysis (led by Matthew K Bagg). The objective of this study is to produce information about the clinical effects of available analgesic medicines for chronic low back pain. This information will be available in a Cochrane review to assist clinical prescription of medicines. The protocol is published and available here.
  3. Prescribing practices of medicines for adults with low back pain: a systematic review (led by Michael Wewege). The objective of this study is to determine how different medicines are prescribed to adults with low back pain and how this differs across countries. The protocol for this study is being developed.
  4. Analgesic medicines for adults with low back pain: a network meta-analysis (led by Michael Wewege). The objective of this study is to evaluate the comparative effectiveness of a range of analgesic medicines for adults across different classifications of low back pain. The protocol for this study has been submitted for publication.
  5. Muscle relaxant medicines for low back pain: a systematic review and meta-analysis (led by Aidan Cashin and Thiago Folly). The objective of this study is to determine the effectiveness and tolerability of muscle relaxant medicines for adults with low back pain. The protocol is available here.
  6. Novel biologic medicines for low back pain: a systematic review and meta-analysis (led by Rodrigo Rizzo). The objective of this study is to determine the effectiveness and tolerability of novel biologic medicines for adults with low back pain. The protocol is available here.

Completed studies:

  1. Evaluation of the impact of unpublished data from clinical trial registries on the effects of medicines for low back pain (led by Matthew Bagg). The objective of this study was to evaluate whether there is a difference between clinical trial data that are published and those that are not published. The findings are published in the Journal of Clinical Epidemiology.
  2. Antidepressant medicines for low back pain: a systematic review and meta-analysis (led by Michael Ferraro). The objective of this study was to determine the effectiveness and tolerability of antidepressant medicines for adults with low back pain. The findings have been submitted for publication. The protocol is available here.

AGReMA – A Guideline for Reporting Mediation Analyses


PROFESSOR JAMES MCAULEY, DR HOPIN LEE, DR AIDAN CASHIN, MATTHEW K BAGG, RODRIGO RIZZO

There are a growing number of studies using mediation analysis to understand the mechanisms of health interventions and exposures. Recent work has shown that the reporting of these studies is heterogenous and incomplete. This problem stifles clinical application, reproducibility, and evidence synthesis. The development and implementation of A Guideline for Reporting Mediation Analyses (AGReMA) will improve the standardization, transparency, and completeness in the reporting of studies that use mediation analysis to understand the mechanisms of health interventions and exposures.

Changes in synovitis and bone marrow lesions may not mediate the effect of cartilage loss on joint pain in osteoarthritis.

A systematic review highlights the need to improve the quality and applicability of trials of physical therapy interventions for low back pain.

The objective of this study was to review and assess the methodological quality of randomized controlled trials that test physical therapy interventions for low back pain. Most trials that test physical therapy interventions for low back pain have methodological limitations that could bias treatment effect estimates. Greater attention to methodological features, such as allocation concealment and the reporting of intention-to-treat effects, would improve the quality of trials testing physical therapy interventions for low back pain.

Items for consideration in a reporting guideline for mediation analyses: a Delphi study.

Mediation analysis is a widely used quantitative method for investigating how interventions and exposures in randomised controlled trials and observational studies have an effect on healthcare outcomes. This study aimed to assess the importance of items that should be considered in a consensus meeting aimed at developing a guideline for reporting mediation analyses. This Delphi study used a rigorous consensus process to reach consensus on 34 reporting items for studies that use mediation analysis. These results will inform a consensus meeting that will consolidate a core set of recommended items for reporting mediation analyses.
