Association of simple hematological parameters with disease manifestations, activity, and severity in patients with systemic sclerosis.

Globally available and inexpensive hematological tests, particularly the NLR and MLR, may be associated with vascular and cutaneous manifestations as well as disease activity and severity in SSc.Key Points• Monocyte count itself independently predicted higher activity and severity scores in SSc.• Globally available and inexpensive hematological markers, particularly the NLR and MLR, may have an association with vascular and cutaneous manifestations as well as disease activity and severity in patients with SSc.
