a. sensitivity
b. specificity
c. likelihood ratio
d. none of the above

A

specificity

17
Q

Sensitivity- proportion of patients (with/without) the condition who have a (positive/negative) test result

A

with

positive

18
Q

Specificity- proportion of patients (with/without) the condition who have a (positive/negative) test result

A

without

negative

19
Q

Sensitivity- tests with high specificity have few false (positives/negatives) –> therefore, a (positive/negative) result (rules out/rules in) the condition

A

negative
negative
rule out

20
Q

Specificity- tests with high specificity have few false (positives/negatives) –> therefore, a (positive/negative) result (rules out/rules in) the condition

A

positive
positive
