Sensitivity
As measured by a questionnaire evaluating the diagnostic test's ability to identify a positive finding when the targeted diagnosis is actually present (i.e. true positive).
Time frame: End of clinician examination, 20 minutes
Specificity
As measured by the discriminatory ability of the diagnostic test to identify if the disease or condition is absent when in actuality it is truly absent (i.e. true negative).
Time frame: End of clinician examination, 20 minutes
Diagnostic accuracy measure of positive likelihood ratio
As measured by sensitivity and specificity values.
Time frame: End of clinician examination, 20 minutes
Diagnostic accuracy measure of negative likelihood ratio
As measured by sensitivity and specificity values.
Time frame: End of clinician examination, 20 minutes
Diagnostic accuracy measure of post-test probabilities
As measured by analysis of the pre-test prevalence of the condition and determination of the post-test shift in probability of the condition.
Time frame: End of clinician examination, 20 minutes
