    Transcript

    00:01 Hello and welcome to epidemiology.

    00:03 You know that smoking is bad for you, right? You know that smoking is probably the most important and prominent risk factor in probably causing lung cancer, but I bet you also know people who have smoked all their lives and lived to be a thousand without having any appreciable illness.

    00:18 And I bet you also know people who have probably tragically succumb to cancer and never having smoked a day in their lives - that’s because exposures don’t necessarily results in disease outcome, it’s just that they are more lucky to do so versus people who aren't exposed to those things.

    00:35 So what we care about is how much of an outcome like lung cancer can we attribute to an exposure like smoking? So today we're gonna talk about attributable risks and you're gonna learn how to calculate two types of attributable risks.

    00:49 We're also gonna change text a bit and talk about something called an odds ratio which is another kind of risk measurement.
