In a case control study the total number of people exposed to the exposure being investigated isn't known, so you can't calculate the true risk or relative risk, which is why we use odds ratio instead!

I love asking people in disease at my school this question :D

Well, what do you have trouble with? Are you not understanding the concepts or are you just having general trouble. It's best to start with basic disease studies and then focus more on this years task, foodborne illnesses.

What diseases should I be studying? Are these (http://www.fda.gov/downloads/Food/Foodb ... 187482.pdf) the only ones we need to know for this event?

Also I am still kind of confused on exactly what we have to do in this event (my first year competing)?

Tests from 2011 and 2012 on the Test Exchange are from the last time the topic was foodborne illness

Are there any resources for examples of statistical analysis questions that I can use?
They can take away everything you have, but they can't take your ability to fight.

I'm not sure what specific things you need help with, but definitely read the Wiki since it covers the basics of each part of the event. The CDC has good 10 minute lessons if you need to study things like epi curves or risk factors. Make sure you know your vocab because every test I've taken except for one has had the same matching section with vocab.

Does anyone have a list of the bare minimum I would need on a cheat sheet for Disease Detectives? I'd like to improve last year's cheat sheet...(It was bad.)
