How much this study counts

  • –A one-time snapshot: it shows a link, not a cause, and cannot show which came first.
  • •The abstract does not say how many people took part.
  • ✓Measured the question itself: aging and age-related disease.
  • •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.
