Newer clinical guidelines suggest using a cut-point value of 120 mmHg for systolic blood pressure to identify a person as being hypertensive. However, some clinicians and researchers have suggested increasing the cut-point value for systolic blood pressure to 130 mmHg to identify hypertension (i.e., those with systolic blood pressure of 130 mmHg and above would be positive for hypertension). If the cut-point value for identifying a person as hypertensive was increased from 120 mmHg to 130 mmHg, which of the following may occur? A. The sensitivity of the new cut-point value would increase. B. The specificity of the new cut-point value would increase. C. Both the sensitivity and specificity of the new cut-point value would increase. D. There would be no change to the sensitivity or specificity of the new cut-point value.

Question
Newer clinical guidelines suggest using a cut-point value of 120 mmHg for systolic blood pressure to identify a person as being hypertensive. However, some clinicians and researchers have suggested increasing the cut-point value for systolic blood pressure to 130 mmHg to identify hypertension (i.e., those with systolic blood pressure of 130 mmHg and above would be positive for hypertension). If the cut-point value for identifying a person as hypertensive was increased from 120 mmHg to 130 mmHg, which of the following may occur?
- A. The sensitivity of the new cut-point value would increase.
- B. The specificity of the new cut-point value would increase.
- C. Both the sensitivity and specificity of the new cut-point value would increase.
- D. There would be no change to the sensitivity or specificity of the new cut-point value.
