Wait, isn't prevalence about existing cases?

Mortality rate is about deaths, not new cases!

Odds ratio and confidence interval seem more statistical, so they don’t fit. I’m pretty confident it’s incidence rate, but I hope I’m not mixing it up!

I’m a bit confused. Isn’t mortality rate about deaths? I feel like I’ve seen a question like this before, but I can’t recall the exact definition.

I remember something about prevalence being related to existing cases, so it can't be that. I’m leaning towards incidence rate too.

I think this might be about incidence rate, but I'm not completely sure. It sounds familiar from our last review session.
