In clinical research, what is a placebo?

Explanation:
A placebo is an inert substance used as a control in clinical trials to separate the drug’s true effects from those caused by expectations or other biases. It looks like the real medication but has no active ingredients, which lets researchers compare outcomes against a neutral baseline. This use in testing of medication is what makes it the best description: it captures both its inert nature and its role in evaluating a drug’s effectiveness. It’s not a measurement instrument, and it’s not an actual medication.
