Suggested answer to Exercise: Regression analyses, 10

Question 10: What would be the effects of adjusting for ponderal index if blood pressure and recovery index were both related to ponderal index?

Suggested answer

If recovery index is related to the adjusting variables, the adjustment will reduce or remove the spurious relationship between recovery index and systolic blood pressure produced by both being independently related to something else. Both the coefficient and its standard error are likely to change.
