How much this study counts

  • ✓Randomized: people were put into groups by chance, so the groups start out alike.
  • –Small: 30 people. Small trials can miss real effects or find chance ones.
  • ✓Measured the question itself: muscle recovery, mood and immune health.
  • ✓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.
