Incomplete ossicular discontinuity.
A: IOD type 1. There is erosion of the long process of the incus but still bony contact between incus and stapes. (I) incus, (M) malleus and (S) stapes. B: IOD Type 2. Incus and stapes are connected mainly by soft tissue.

ROC curves for scenarios 1 and 2.
Receiver operating characteristics curves (n = 328) for the HfCHL test. Scenario 1 (in black): Target group for the test (disease group) included all patients with incomplete ossicular discontinuity. Scenario 2 (in red): Target group for the test (disease group) exclusively included patients with type 2 IOD.
