The Disease Detectives Wiki is always a good place to start, as is the event page on soinc.org. Basically, this event focuses on epidemiology, so you should be able to examine various aspects of how diseases spread, etc. Can't say I've done this event myself, but plenty of people who have contributed to the Disease Detectives Wiki, and you can learn a lot from it.

Indeed so ;)

So, my original post was edited to be correct, but forgot the quoted one.

Here's some food for thought.

Q: Given a case-control study;

a=exposed case patients,b=control exposed,c=unexposed case patients,d=unexposed control

a=50
b=22
c=43
d=12

Complete the following:
-Calculate the odds ratio.

-What does the odds ratio suggest?

How do you work through the relative risk equation and relative risk tells you how much more likely it is to to get a disease in a certain environment/situation relative to another right?

Relative risk = (a/(a+b))/(c/(c+d)), where a,b,c,d refer to cells in your standard 2*2 table. And you are basically correct, it measures strength of association between exposure and outcome. It is only used in cohort studies.

OR=(50*12)/(22*43)=0.634. This suggests a protective factor in the given exposure

Can anyone help me with writing good case definitions? As far as I know, it's just person-place-time, but I was wondering if there are any other specifics I should be aware of/any practice out there specifically for this topic. Thanks!

Can anyone give me some good study links? Im having trouble understanding this event and am short of some information. I have 15 days until my first competition and really need some good links. Thanks.

Some people add clinical features as a fourth element. Others consider that part of "person."
