Measures of Association
Odds
chances of something happening
odds for = likelihood something will happen
odds against = likelihood something won't happen
= probability something will happen/probability something WONT happen
Odds Ratio
OR = 1
no difference/association
OR < 1
decreased odds of risk
OR > 1
increased odd of risk
= odds of exposure among cases/
odds of exposure among non-cases
used in
case-control studies
a ratio of the frequency of an event occurring to the frequency of it not
Risk
probability of an event/outcome taking place in a specified time period
relationship between exposure and outcome among groups
risk difference = difference in risk of outcome dependent on exposure of two bodies
Relative Risk
associated with exposure
risk of an event happening after exposure compared to it happening following no-exposure
= incidence of disease in exposed/
incidence of disease in non-exposed
RR = 1
no difference between exposed and non-exposed
RR < 1
risk decreased
RR > 1
risk increased
cannot use in case-control studies
used in
cohort studies
chances of something happening/
chances of something NOT happening
a probability
mathematical comparisons
absolute
subtraction
something is more or less than something else
relative
division
something is 'twice as much' or 'less than half' compared to something else
