Approximately twice as many meta-analyses have been done on vitamin D supplements for falls and fractures as randomized trials. Conclusions of these meta-analyses differ largely because of the methods adopted, such as the choice of studies included (2, 3). LeBlanc and colleagues assessed the effectiveness of vitamin D supplementation on mortality, falls, and fractures in vitamin D deficiency, including 11, 5, and 5 trials, respectively, for each outcome. In contrast, we included 38, 20, and 23 trials, respectively, in meta-analyses of vitamin D supplementation for these conditions ...References1. LeBlanc ES, Zakher B, Daeges M, Pappas M, Chou R.
