High sensitivity and high specificity
High sensitivity and low specificity
Low sensitivity and low specificity
Low sensitivity and high specificity
Answer- B. High sensitivity and low specificity
The line in red shows the new test curve distribution is shorter than old thus, the 95% CI range of new test will be more precise than the old test. For a particular cut off point, the sensitivity of the new test will be high since the 95% CI is precise for the new test than the old test. So, high sensitivity is achieved at the expense of a decrease in specificity.
