Based on clinical trial results that found treating "mild hypertension" could significantly prevent stroke, the cut-point for defining abnormal diastolic blood pressure was lowered from 110 mm Hg to 90 mm Hg. With this new cut-point, would you expect the specificity of diastolic blood pressure as a test for hypertension become higher, lower, or unchanged? (choose the one best answer)

Higher specificity

Lower specificity

Unchanged specificity
