Applying Evidence & Shared Decisions

Translate research into a balanced conversation that respects baseline risk, practical constraints and personal goals.

Answer all 10 questions, then submit to see your score and explanations. This is a self-study exercise; results are not saved.

Question 01. Events decrease from 10% to 8% over one year. What is the absolute reduction? A. 2 percentage pointsB. 20 percentage pointsC. 8 percentage pointsD. 80 percentage points

Question 02. For an absolute reduction of 0.02, what is NNT? A. 2B. 50C. 20D. 0.5

Question 03. Which explanation best supports understanding of a risk reduction? A. The treatment is impressiveB. Only the relative reduction without baseline riskC. Only the p-valueD. Two fewer events per 100 people over one year

Question 04. What should happen when a patient’s priorities differ from the clinician’s initial preference? A. Ignore the patient’s goalsB. Assume the research no longer existsC. Explore the trade-off and reasonable options togetherD. Change the published event counts

Question 05. When is additional testing especially useful? A. Whenever a test is available regardless of consequencesB. Only when no uncertainty existsC. When the result will certainly be ignoredD. When the result could change a meaningful management decision

Question 06. Which comparison most fairly presents benefit and harm? A. Relative benefit and absolute harm with no explanationB. Different follow-up periods concealed from the patientC. Only the benefit graphD. Common denominators and comparable time horizons
