For a result to be clinically important, what two things must happen?

• A. The change must have value to the patient and be large enough to make a difference in a patient's life
• B. The change must achieve a statistically significant p-value and a large effect size
• C. The change must be cost-effective and easily implementable in practice
• D. The change must be approved by regulatory guidelines

Answer: (A)

The key idea is that clinical importance comes from a result that patients value and that changes real-life outcomes in a meaningful way. It isn’t enough for an effect to be detectable in a study or statistically unlikely to be due to chance; it must matter to the patient and be large enough to make a real difference in daily life or health status. That’s why the best choice says the change has value to the patient and is large enough to affect a patient’s life. If a result patients don’t perceive as beneficial or that doesn’t translate into noticeable improvements in their health or functioning, it won’t be clinically important, even if the statistics look solid. Conversely, an effect that patients value and that meaningfully improves outcomes is what clinicians and stakeholders consider clinically important. The other options mix statistical significance, magnitude, practicality, or regulatory approval. A result can be statistically significant without being meaningful to patients, a large effect size alone doesn’t guarantee patient-perceived benefit, and cost, ease of implementation, or regulatory approval don’t by themselves establish clinical importance.
