What is RR (Risk Ratio)?
What is the formula for it? 

Definition
think: when you are exposed to __, what is the likelihood you will die out of all people with that exposure
I_{1}_{ }= a/(a+b)
I_{0}_{ }= c/(c+d)



Term
if one asked:
Is exposure associated with greater risk of disease?
what formula would that refer to? 

Definition
RR, becuase it asks about risk (RR) and exposure (incidence measurement) 


Term
if one asked:
Is exposure associated with greater odds of disease?
what formula would that refer to?


Definition


Term
if one asked:
What is the excess risk (incidence) of disease associated with exposure?
what formula would that refer to? 

Definition
RD, think excess > difference 


Term
if one asked:
What proportion of disease occurence among exposed indivdiuals is due to the exposure?
what formula would that refer to? 

Definition
AR(E):
(I_{1}I_{0})/I_{1}
RD/I_{1}, relize that proportion means two different values 


Term
if one asked:
What proportion of disease ocurrence in the total population is due to exposure?
what formula would that refer to?

Term
What is RD (risk difference)? 

Definition


Term
What is AR(E), attributable risk among the exposed 

Definition
(I_{1}I_{0})/I_{1} or RD/I_{1}
think risk > incidence
think attributable > look at nonexposed (I_{0}_{)} 


Term
What is PAR, population attributable risk 

Definition
(II_{0})/I
where I is (a+c)/(a+b+c+d) 


Term
What is the formula for risk.
I_{n} = x/(x+y) 

Definition


Term
if one asked:
Is the exposure associated with death, relative to nonexposure
what formula would that refer to? 

Definition


Term
if one asked:
What proportion of th death was due to exposure?
what formula would that refer to?
