Association And Causation

What is the definition of relative risk?

• A statistical measure that compares the risk of a certain event or outcome within the same group or population.

• A statistical measure that compares the risk of a certain event or outcome between two groups or populations.

• A measure of the risk of a certain event or outcome within a specific time frame.

• A measure of the risk of a certain event or outcome within a single group or population.

How is relative risk calculated?

• By subtracting the probability of an event occurring in one group from the probability of the same event occurring in another group.

• By multiplying the probability of an event occurring in one group by the probability of the same event occurring in another group.

• By adding the probability of an event occurring in one group to the probability of the same event occurring in another group.

• By dividing the probability of an event occurring in one group by the probability of the same event occurring in another group.

What does a relative risk of 1 mean?

• Slightly increased risk

• Significantly increased risk

• Slightly decreased risk

• No difference in risk

If the relative risk is greater than 1, what does it indicate?

• The exposure or risk factor has no effect on the likelihood of the outcome or disease.

• The exposure or risk factor decreases the likelihood of the outcome or disease.

• The exposure or risk factor increases the likelihood of the outcome or disease.

• The exposure or risk factor is unrelated to the likelihood of the outcome or disease.

What is the interpretation of a relative risk less than 1?

• The exposure or treatment has no effect on the risk of the outcome.

• The exposure or treatment is associated with a lower risk of the outcome.

• The exposure or treatment is associated with a higher risk of the outcome.

• The relative risk cannot be determined.

The probability that an event will happen

• Risk

• Odds

• Incidence

• Prevalence

The increase or decrease in the risk (or rate) of disease in the exposed group that is attributable to exposure

• Relative Risk

• Odds Ratio

• Attributable Risk

• Atributable Fraction

The proportion of disease that can be prevented if the exposure can be averted

• Atributable Risk

• Atributable Fraction

• Risk Difference

• Incidence Rate

The proportion of disease in the population that is due to the exposure

• Population Risk Ratio

• Population Relative Risk

• Population Attributable Risk

• Population Attributable Fraction (PAF)

A ratio of probability of an event is occured to probability of an event is not occured

• Odds

• Risk

• Incidence

• Prevalence
