  • *The basis for the assumed risk is the rate of events in the bisphosphonate group. The corresponding risk (and its 95% CI) is based on the assumed risk in the comparison group and the odds ratio of the intervention (and its 95% CI).

  • GRADE, Working Group grades of evidence: 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; very low quality—we are very uncertain about the estimate.
