Eight studies were included in the review (709 patients; range 35 to 178). Only one study reported the follow-up period which was approximately 29 weeks. The quality of the studies varied: six studies described method of randomisation; two studies reported comparable groups at baseline, one study reported blinding, six studies reported relevant endpoints, six studies reported number of drop-outs and three studies reported an intention-to-treat analysis.
Muscle function (six studies): Two studies reported statistically significant improvements in muscle function for intervention groups compared with control groups at follow-up.
Activities of daily living (six studies): One study reported statistically significant improvements in activities of daily living for the intervention group using family style meals compared with ordinary food at follow-up.
Weight changes (eight studies): Six studies reported statistically significant improvements in weight in intervention groups compared with control groups at follow-up.
Overall, there was concordance in five of the eight studies.
