Question: Screening Calculations

Muscle tension dysphonia (MTD) can masquerade as adductor spasmodic dysphonia (ADSD), leading to diagnostic confusion. An investigation assessed the diagnostic worth of acoustic analysis of phonatory breaks (PB) as a possible objective test to distinguish ADSD from MTD.

Acoustic Analysis of Phonatory Breaks to Test for ADSD and MTD (n=100)

Reference Standard Reference Standard
Test Outcome Has ADSD Has MTD
Positive (PB≥40 ms) 27
True Positive (TP) 		25
False Positive (FP)
Negative (PB<40 ms) 14
False Negative (FN) 		34
True Negative (TN)
