On page 3363 in the 18 October 2012 issue, there are errors in Figure 2B. On the y-axis (“Anti–Pgingivalis IgG [median OD 490 nm]”) of the Figure 2B graph, there is illegible text between each of the y-axis values. There should be no text between these values. The corrected Figure 2 is shown below.
Sequence homology between the β22GPI peptide and P gingivalis and anti–P gingivalis immunoreactivity. (A) Sequence homology between β2GPI peptide and P gingivalis. (B) Box-whisker plots of anti–P gingivalis IgG in patients with SLE and APS positive for anti-β2GPI peptide IgG (A group), subjects with moderate chronic periodontitis (B group), and healthy subjects without periodontitis and autoimmune diseases (C group). Median, quartiles, range, and possibly extreme values are indicated. Statistical analysis was performed with the Mann-Whitney test. *P < .001 compared with the C group.
