What is attributable risk?

The risk on disease which is attributable to exposure
The absolute risk (incidence) in exposed vs absolute risk in non-exposed

What is the best way to balance out all extraneous variables between groups?

Randomization, however it is usually not possible to study risk or prognostic factors this way.

What are extraneous variables?

Is a general term for variables that are part of the system being studied but are not the exposure and disease of primary interest. Also known as covariates
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding

What is multivariable analysis?

Allows for consideration of many variables simnultaneously.
Cohort and case control typically rely on logistic regression
Survival analyses -> cox proportional hazard model

Why should you not use only one method for controlling confounders?

Because each methods has its strengths and weaknesses
They do not deal with risk or prognostic factors that are not known at the time of the study.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
