Frequently Asked Questions
Does a comparison establish which treatment is better?
Only appropriately designed evidence for the same clinical question can support that conclusion. Database categories and mechanisms alone cannot rank treatments.
Does this page establish that these compounds can be combined?
No. This page does not assess interactions or the benefit and safety of combined use. Individual studies cannot establish the effects of a combination.
