  1. Cut off

    This study clearly show us that the cut-off at 2,6 for the pectoralis minor length test is inappropriate. Though, I do not understand why it is necessary to calculate sensitivity, specificity and likelihood ratios with this cut-off that is obviously out of the normal values (as provided by Borstad). Table 5 and 6, and the conclusions based on them, is therefore of lesser interest. I wonder if there was done a ROC analysis to check the diagnostic properties? Are other cut-offs more suitable?
