A systematic review of workplace interventions to prevent low back pain

CRD COMMENTARY:

This was a good review of the area. The research question and inclusion and exclusion criteria were clearly stated. The literature search appears to have been thorough, although the searches were limited to English language publications and did not include unpublished data or data published as an abstract. It is possible that additional studies were missed. The author reported who, and how many of the assessors, performed the selection of studies and the validity assessment. The author did not report who extracted the data. The validity of the included studies was assessed, and this information was used to assess the impact of the results in a level of evidence table.
The review was a narrative discussion with no statistical pooling, which was appropriate given the nature of the evidence. Differences between the studies were discussed and investigated using sensitivity analyses.
The author's conclusions appeared to follow from the results.
