In Reply Bolland and colleagues question the inclusion of trials of vitamin D analogues in our meta-analysis. This meta-analysis was an update of prior meta-analyses conducted for the US Preventive Services Task Force (USPSTF) to inform recommendations on use of vitamin D for prevention of falls in primary care settings.1,2 As in the prior USPSTF analyses, we included trials that evaluated vitamin D analogues and did not exclude them on a post hoc basis. Inclusion of vitamin D and vitamin D analogues is appropriate given the similar mechanisms and action and variability in how vitamin D deficiency is treated.
