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
I1 = a/(a+b)
I0 = 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):
(I1-I0)/I1
RD/I1, 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? |

| What is RD (risk difference)? |

Definition
|
|
Term
| What is AR(E), attributable risk among the exposed |
|
Definition
(I1-I0)/I1 or RD/I1
think risk --> incidence
think attributable --> look at non-exposed (I0) |
|
|
Term
| What is PAR, population attributable risk |
|
Definition
(I-I0)/I
where I is (a+c)/(a+b+c+d) |
|
|
Term
What is the formula for risk.
In = x/(x+y) |

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

|
Term
if one asked:

what formula would that refer to? |
