What the study found

Points to benefit

Among adults with moderate or worse hearing loss who met the guideline, risk of death from any cause was 71% lower (HRadjusted = 0.29; 95% CI: 0.10-0.83; P = 0.02). 152 people died.

How much this study counts

  • –Shows a link, not a cause: people chose their own habits, and other differences between them may explain the result.
  • ✓Followed people over time, so habits were recorded before the outcome happened.
  • •1,482 people.
  • ✓Measured the question itself: death from any cause and healthy aging.
  • •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.
