NEMO score in nailfold videocapillaroscopy is a good tool to assess both steady state levels and overtime changes of disease activity in patients with systemic sclerosis: a comparison with the proposed composite indices for this disease status entity

Table 2 Prevalence in the cohort of the different items included in DA composite indices at T0

	Item	Number (%) of patients
In EUSTAR index only	mRSS > 18	7 (7.1)
	mRSS up to 18	91 (92.9)
	Tendon friction rubs	29 (29.6)
	CRP > 1 mg/dL	12 (12.9)
	DLCO < 70% of the predicted value	47 (48)
In EScSG index only	mRSS > 14	12 (12.9)
	Scleredema	60 (61.2)
	∆ Vascular	52 (53.0)
	Arthritis	23 (23.5)
	DLCO < 80% of the predicted value	67 (68.4)
	∆ Cardiopulmonary	18 (18.4)
	ESR > 30 mm/1st h	25 (25.5)
	Hypocomplementaemia (C₃ and/or C₄)	11 (11.2)
In both EScSG and EUSTAR	∆ Skin	27 (27.6)
In both EScSG and EUSTAR	Digital ulcers	30 (30.6)
