What the study found

Points to benefit

After 12 months, the program group scored 0.85 points higher on the physical performance test (SPPB; 95% CI, 0.44 to 1.26, P < 0.0001). No group difference was found in death, hospital stays or other secondary outcomes.

How much this study counts

  • ✓Randomized: people were put into groups by chance, so the groups start out alike.
  • ✓Large: 964 people.
  • ✓Long: about 1 year.
  • •Measured other health measures, not death from any cause and healthy aging itself.
  • •The PubMed record has no conflict-of-interest statement.
  • •Summarized from the PubMed abstract only. The full paper may hold details the abstract leaves out.

✓ Strength– Limit• Note

These points come from fixed rules about the type of study, its size and length, what it measured, and who has a stake. Every study on Digestery gets the same rules.
