PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

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?
