Review of the bone mineral density data in the meta-analysis about the effects of exercise on physical outcomes of breast cancer survivors receiving hormone therapy

This study concludes that exercise has possible effects on bone mineral density (BMD) in breast cancer survivors despite the absence of statistically significant results in this regard. Furthermore, as the authors point out, the results show an enormous heterogeneity that makes their interpretation almost unfeasible. Despite the possible sources of heterogeneity detected by the authors, there are others that do not seem to have been discussed and that we believe should be considered.
