ELI5: Explain Like I'm 5

COSTART

Costart is like a cool way for doctors and scientists to write down the names of the boo-boos or sicknesses that people have. It's like a super secret code that helps them talk about different kinds of hurties, but nobody else can understand it unless they know the code too. So, when a doctor or scientist writes "headache" in Costart, they write it like "HEADACHE(1)" so they know it means a certain kind of headache. It helps them keep track of all the different types of hurties and try to find ways to make them better.
