Infection & Response: Double-Blind Trials 💊 GCSE Biology Learning & Revision

This episode discusses double-blind clinical trials.

Double-blind clinical trials are designed to eliminate bias by ensuring neither patients nor doctors know who receives the actual drug or a placebo. 

This method maintains fairness by preventing any preconceived notions from influencing the results. Crucially, all other conditions are kept the same for both groups, ensuring that the drug's effect is the sole variable impacting patient health. 

The goal is to obtain an objective assessment of the drug's effectiveness, free from subjective interpretations or expectations.
