SLE: systemic lupus erythematosus, Ro(+)La(−): anti-Ro/SS-A-positive but anti-La/SS-B-negative, Ro(+)La(+): anti-Ro/SS-A- and anti-La/SS-B-positive, Ro(−)La(−): anti-Ro/SS-A- and anti-La/SS-B-negative SLE patients. OR: odds ratio, CI: confidence interval, Pc: corrected P value, NS: not significant. Allele frequencies are shown in parenthesis (%). Associations were established by Fisher’s exact test using 2×2 contingency tables.
