I do NOT Understand this event. Can someone help me?

Try taking a look at the 2014 training PowerPoint on the national website (link).

I am sorry, but the link does not seem to work. Can you please check if it is updated?

Oh, it should work now. I apparently don't know how to copy-paste.

Not found again!

Not found again!

So, my original post was edited to be correct, but forgot the quoted one.
Either way, here is the link unambiguously:

It worked! Thank you!

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."
