EBP Diagnostic Stats

True negatives / (true negatives + false positives)

Reflects the likelihood or probability that your patient has a disease or a functional condition

Calculate PPV

What is true about likelihood ratios?

Reflects the tests ability to detect a disease or functional condition compared to a reference standard

If you want to eliminate false negatives you choose a ?

Which RULES IN the disease with a positive test result?

Which is a False Negative?

Which is a True Negative?

The ability of the test to detect those patients who DO NOT have the disorder, as established by a gold standard

Which is a False Positive?

If you want to eliminate false positives you choose a ?

Patient, Intervention, Comparison, Outcome

Calculate Specificity

This question below is a _______ type of question

Calculate Sensitivity

Those people identified by the test as NOT HAVING the pathology who DO NOT in fact have the pathology

If you’re increasing your false negatives, you are decreasing your__?

What happens if you decrease the cutoff point for TUG in regard to True/False Positives and True/False Negatives?

Those people identified by the test as HAVING the pathology ho actually DO have the pathology

Which is a True Positive?

Those people identified by the test as HAVING the pathology who DO NOT have the pathology

Which type of Row Summary is this?

Which test RULES OUT the disease with a negative test

If you’re decrease your false positives, you are increasing your__?

Those people identified by the test as NOT HAVING the pathology who actually DO in fact have the pathology

True positives / (true positives + false negative)

+LR = Sensitivity/(1-Specificity)

True positive rate

What happens if you increase the cutoff point for MMT in regard to True/False Positives and True/False Negatives?

-LR = (1-Sensitivity)/(Specificity)
