| pubmed-article:1891322 | pubmed:abstractText | An exercise/sleep model from past research was tested for relationships with a quality of life measure of the health status of 126 elderly persons. Past statistical analyses of this relationship used canonical correlation statistical analyses. In the following study, when structural equation analysis (LISREL VII) was applied to the same data, an altered model resulted: an exercise-only model. To examine this relationship further, researchers should employ a longitudinal design with a more comprehensive model and larger sample of elderly persons. | lld:pubmed |
