FAQ

Common questions

Does a high score prove the treatment works?

No. A high score means the study design has stronger reliability features. The actual result, effect size, population, harms, and replication still matter.

Why do conflicts of interest affect the score?

Conflicts do not automatically invalidate a study, but they raise the need for transparency, independent replication, and careful reading of outcomes.

Can observational studies score well?

They can score as useful evidence for safety signals, associations, or rare outcomes, but they usually cannot establish treatment effects as cleanly as randomized controlled trials.
