One journal missing

The additional file presented together with the paper by McKibbon et al (1) provides the list of the 170 journals read for 2000 along with the number of articles reviewed, the number and percentage that passed criteria, and the NNR (number of articles that are needed to be read to obtain one that is clinically relevant and has high-quality methods). In this list one journal is missing.

Comparing this list with the list available at the Hedges website the information on Acta Obstetricia et Gynecologica Scandinavica appears to be missing. This journal is cited in the results section as the journal with the highest NNR to obtain one high-quality and clinically relevant study or review for internal medicine, i.e. one article abstracted or noted in ACP J Club. According to Table 2 several other journals appear to have a higher NNR.

In Table 2 Acta Obstetricia et Gynecologica Scandinavica is the first of a long list of journals sorted alphabetically having no article abstracted in ACP J Club and thus an NNR to obtain one article abstracted in ACP J Club equal to infinity. For Acta Obstetricia et Gynecologica Scandinavica that information is missing in Table 2.
