*Logistic regression also adjusts for mouth ulcer, pulmonary hypertension, cranial or peripheral neuropathy, which are not shown in the table because association is not statistically significant,
†Cox regression was also adjusted for pancreatitis, anti-Sm, which are not shown in the table as they were not statistically significant.
‡Blank cell indicates the clinical feature was not selected into corresponding multivariate analysis.
