*
P-values comparing the difference between the organ involvement with scleroderma patterns of capillaroscopy between the two groups of patients including SSc-OS syndrome patients and LcSSc patients (p-value*) were considered significant if < 0.05. No significant relationship was found between capillaroscopy patterns and organ involvement in two groups.
DU – digital ulcer, LcSSc – limited cutaneous systemic sclerosis, OS – overlap syndrome, PAH – pulmonary arterial hypertension, SSc – systemic sclerosis.
