Blinding in Clinical Trials
8. Triple Blind
A triple blind trial means that participants, clinicians, data collectors, outcome adjudicators and data analysts do not have access to details of group assignment. This ensures that bias for or against the tested treatment is very unlikely to occur.
- Medicine may still be labelled as A or B during analysis.
- Analyst is blinded to which treatment is which.
- Helps to avoid bias in the analysed results.
