Definitions of sensitivity and specificity

Definition and examples of specificity and sensitivity

The discussion of sensitivity and specificity is a bit confusing, in part because it is not made completely explicit what is meant by 0/1, dead/alive and positive/negative. I think here death is the "positive" outcome, which is fine, but then the definition of specificity needs to change I think. (Or maybe I am just confused)

It could definitely be clearer and I'm pretty sure I mixed things up at some point myself! I'll take a look at improving this.
