What is the definition of Controlled Studies?

"Controlled studies" are like the secret recipe of a high-end cocktail but with a side of science. They're experiments where researchers carefully manipulate variables to see what happens, much like a magician pulling the strings from behind the curtain. Imagine it as a well-oiled machine where every variable is a prop, every observation a plot twist, and the outcome is the ultimate showstopper of scientific truth.
