Hence, systemic lupus erythematosus, discoid lupus erythematosus, scleroderma/CREST (calcinosis, Raynaud phenomenon, esophageal motility abnormalities, sclerodactyly, and telangiectasia), Raynaud syndrome, SS, MCTD, overlap CTD syndromes, polymyositis, and dermatomyositis were considered disease-positive [11] and all other diagnoses were considered disease-negative.
The most common diagnosis was systemic lupus erythematosus (n = 16), followed by Raynaud syndrome (n = 6), SS (n = 6), scleroderma/CREST (n = 5), MCTD (n = 3), discoid lupus erythematosus (n = 2), dermatomyositis/polymyositis (n = 2), and an undefined CTD (n = 9).
