Abstract
Low serum levels of vitamin D have been described in patents with a variety of underlying diseases, an issue we recently considered in patients hospitalized with coronavirus disease-19, or COVID-19, infections1 . Appel et al noted that such a situation exists for elderly individuals who suffer falls and that the evidence from randomized clinical trials (RCTs) regarding vitamin D supplementation to prevent such events is contradictory and has even led to conflicting recommendations2 .

The results of this trial were the major content of the paper by Appel et al This article is protected by copyright. All rights reserved.
