This page documents how this source is reused across Claim by Claim. A source can support, challenge, qualify or contextualize different claims; appearing here does not imply endorsement of every linked proposition.
Evidence context
Evidence roles describe what this source helps establish inside each Investigation. They are local to that use, not permanent labels attached to the publication itself.
Investigation
A placebo-controlled atopic-dermatitis study found no clear added benefit; a 2014 smoking-cessation sham comparison reported a positive signal but alternated assignments, used telephone self-report and had reporting/industry limitations. Neither validates broad disease diagnosis or treatment.
