A positive association between antivinculin antibody levels and GI symptom severity is reported in SSc.

In the univariate analyses, patients who were positive for antivinculin antibodies were more likely to have limited cutaneous disease (odds ratio [OR] 9.60 [95% confidence interval (95% CI) 1.19, 77.23]) and thyroid disease (OR 4.09 [95% CI 1.27, 13.21]). Such patients were also less likely to have lung involvement based on a Medsger Severity Score of \u22652 (OR 0.25 [95% CI 0.07, 0.92]). Higher levels of antivinculin autoantibodies were associated with less gastric emptying (\u03b2 coefficient \u20133.41 [95% CI \u20136.72, \u20130.09]). The association between antivinculin antibodies and each of these clinical features remained significant in the multivariable model. In particular, the presence of antivinculin antibodies (\u03b2 coefficient \u20136.20 [95% CI \u201312.33, \u20130.063]) and higher levels of antivinculin antibodies (\u03b2 coefficient \u20133.64
