From: A systematic review, and meta-analyses, of the impact of health-related claims on dietary choices
Bias domain | Source of bias | Health-related claims studies |
|---|---|---|
Selection bias | a. Random sequence generation | Were participants/products randomised to the health-related claim condition? |
b. Allocation concealment | Were participants aware of claim allocation? | |
Performance bias | Blinding of participants and personnel | Were participants blinded to the aims of the study? (e.g. the impact of health-related claims on purchasing/consumption) |
Detection bias | Blinding of outcome assessment | Were participants aware of the study outcomes? |
Other bias | Anything else | How were participants recruited? Were participants/products representative of the target population? How was the study funded? Were there any conflicts of interest reported? |
