Contributions of authors

AM: screened retrieved papers against inclusion criteria, appraised risk of bias and extracted data from papers and wrote parts of the Background in the updated review.

EE: conceived the review and provided clinical perspective. Designed and coordinated review, participated in retrieval of papers, screened retrieved papers against inclusion criteria, appraised quality of papers, extracted data from papers, wrote parts of the updated review (Abstract, Applicability of evidence, Agreements and disagreements with other studies or reviews).

EM: developed the search strategy, organized retrieval of and screened retrieved papers against inclusion criteria in original review, appraised risk of bias of papers, extracted data from papers, meta‐analyzed data, compiled Characteristics of included studies; Characteristics of excluded studies tables. Wrote Methods and Results Section and parts of Discussion (Summary of main results, Overall completeness of evidence, Quality of the evidence; Potential biases in the review process).

Notes

This review is no longer being updated, but is correct at the time of publication. Reviews of the individual opioids are underway and the review will eventually be replaced by an overview.

Population
Intervention
Comparison
Outcome

The PICO model is widely used and taught in evidence-based health care as a strategy for formulating questions and search strategies and for characterizing clinical studies or meta-analyses. PICO stands for four different potential components of a clinical question: Patient, Population or Problem; Intervention; Comparison; Outcome.

See more on using PICO in the Cochrane Handbook.
