Abbreviations: Anti-dsDNA, anti-double-stranded DNA; anti-Rib-P, anti-ribosomal P; anti-Sm, anti-Smith; SLE, systemic lupus erythematosus. Values represent mean ± standard deviation for concentrations in U/ml and proportions of positives. Differences were assessed using the t-test for continuous variables or the χ2 or Fisher’s exact test for proportions.
