Study	Nailfold capillaroscopy/microangiopathy in the criteria for SSc and RP
LeRoy et al. 86	NVC included as a parameter in the criteria for the classification of early systemic sclerosis
Lonzetti et al. 87 Cutolo and Matucci Cerinic 88	NVC increases the sensitivity of American College of Rheumatology classification criteria for limited scleroderma
Avouac et al. 89	NVC included in the VEDOSS criteria for very early SSc diagnosis
Van den Hoogen et al. 90	NVC patterns included in the new European League Against Rheumatism and American College of Rheumatology criteria for SSc
Maverakis et al. 91	NVC included in the diagnostic criteria for primary RP
Cutolo et al. 74	The presence of SSc-specific autoantibodies and/or abnormal nailfold capillaroscopy (LeRoy and Medsger Criteria) may be used to select patients for clinical trials

NVC: nailfold videocapillaroscopy; VEDOSS: very early diagnosis of systemic sclerosis.
