which parameter in which file best describes how sensitive a cell line is to knockout?

I am looking through all of the files at DepMap Data Downloads. It seems that there are so many options it’s hard to decide which file I need. I need information on any kind pf parameter that tells me how easy it is to knock out a given cell line.
Thanks, csmatyi
