Contributions of authors

For the original review (2001) Anthony Kelly (AK) and Josephine Kavanagh (JK) performed the original data extraction. AK, JK and Jane Thomas (JT) drafted the original review. For this update (2014), additional trials were assessed and the data were extracted by JT and Anna Fairclough (AF), JT and AF redrafted the review and this final draft was reviewed by JK and AK. Changes following editorial review were completed by JT and AF, and reviewed by AK and JK.

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.

High quality: Further research is very unlikely to change our confidence in the estimate of effect.
Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.
Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
