^f.Limited to those tested for all three auto antibodies (510).

^g.The multivariate model contains all factors with an adjusted p-value <0.10 to account for potential confounding, but only p-values <0.01 are considered statistically significant in this analysis. Factors with blank entries in the multivariate columns were excluded from the model because p ≥0.10.
