Questions and Answers

What was the Crude Relative Risk for the association between social isolation and depression?

  • 1.20
  • 3.00
  • 1.80 (correct)
  • 2.50
  • What can happen if a factor which lies in the causal pathway between exposure and outcome is treated like a confounder and adjusted for?

  • Collider bias
  • Overadjustment (correct)
  • Residual confounding
  • Confounding by indication
  • Why might the age-adjusted estimate be lower than the Crude Relative Risk?

  • Because age is not a confounder
  • Because age is not associated with depression
  • Because age is a confounder that explains part of the association (correct)
  • Because age is not associated with social isolation
  • What occurs when researchers adjust for some but not all potential confounders or the confounders adjusted for are not accurately measured?
