What the study found

No difference

Urine taurine was linked to digit span scores in men and to word fluency overall, but none of these links held after correcting for multiple tests.

How much this study counts

  • –A one-time snapshot: it shows a link, not a cause, and cannot show which came first.
  • •560 people.
  • •Measured other health measures, not aging and age-related decline itself.
  • ✓No competing interests declared.
  • •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.
