Evidence for this outcome begins at low quality as it is comprised of observational studies.
Change in treatment is a surrogate for patient-important outcomes as it remains unknown how or if change in treatment influences patient-important outcomes.
Very few of the best practices for reducing bias in this study design were reported in the article. See Appendix 2, Table A1, for full risk of bias assessment.
In Canada, treatment options and combinations differ from those studied, and treatment patterns are much more conservative overall, especially for low-risk patients.
