To the Editor To investigate whether exercise improves functional status in patients with hip fractures, Dr Latham and colleagues1 conducted a randomized clinical trial in which participants were assigned to either a home-based exercise program (intervention) or telephone-based cardiovascular nutritional education (control). Modest benefits in the main outcome were reported by the authors and seem important because costly and intensive exercise programs that require professional supervision and equipment had previously demonstrated benefits2; thus, lower-cost alternatives would be useful. However, some aspects of this study need to be clarified for a better understanding of the results.
