Five checks before changing your routine

  1. Confirm the population matches the people you care about.
  2. Identify the intervention, comparator, and outcome actually studied.
  3. Separate statistical significance from a meaningful real-world effect.
  4. Check follow-up length, withdrawals, funding, and stated limitations.
  5. Read the full paper or qualified guidance before applying a conclusion.
