Erratum To: The PTPN221858C/T polymorphism is associated with anti-cyclic citrullinated peptide antibody-positive early rheumatoid arthritis in northern Sweden

The Original Article was published on 06 June 2007

After publication of our recent article [1], we noticed an error in Table 6 'Relative risk for developing rheumatoid arthritis in patients, stratified for anti-cyclic citrullinated peptide (anti-CCP) antibodies'.

Under the heading of 'Anti-CCP antibody-positive', the first line should read 'HLA-shared epitope-negative', and the second line should read 'HLA-shared epitope-positive'. Similarly, under the heading 'Anti-CCP antibody-negative', the first line should read 'HLA-shared epitope-negative' and the second line should read 'HLA-shared epitope-positive'.

The correct table is given here as Table 1 (a corrected version of Table 6 [1]).

Table 1 Relative risk for developing rheumatoid arthritis in patients, stratified for anti-cyclic citrullinated peptide (anti-CCP) antibodies
