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.

CAL of severe periodontitis (case definitions for periodontitis Page and Eke, 2007)

While I was browsing Roos Leroy et al. paper,  2010, BMC OH (Methodological issues in epidemiological studies of periodontitis) I noticed that authors displayed severe periodontitis according to case definitions for periodontitis (Page and Eke, 2007) in table 1 as  2 interproximal sites with CAL ≥ 4??? Which is supposed to be 6 as displayed in table 13 in the original paper J periodontology 2007;78:1387-1399, I am sure that is a typing error but it may create overestimation of severe periodontitis and overlap with moderate cases
