What are clinical trials?

What is bamboo?
A process which assigns individual study participants to into two groups that are exactly the same, but one group gets the treatment, and the other does not.
What is randomization?

What are controls?
The mixing of effects between an exposure, an outcome, and a third variable.
What is confounding?

What is the counterfactual ideal?
This is a strength of a case-control study.
What are efficient for rare diseases, efficient for diseases with long latency and induction periods, and can evaluate multiple exposures when little is known about a disease?
An error that results from procedures used to select subjects into the study or the analysis.

What are inefficient for rare exposures, poor information due to retrospective nature of case-control studies, vulnerable to bias due to the retrospective nature?

What are losses to follow up?
