Table 2.

Factors associated with discordance (≥2point difference, with higher score indicating poorer functioning/more severe disease) in gVAS scores between PF and MD (all p < 0.01), and those with no effect on discordance

Patient/Family gVAS score higher	Physician gVAS score higher	No effect on discordance
Poorer CHAQ scores	Muscle enzyme abnormalities	Current age/age of onset
Poorer Quality of Life scores	Proximal muscle weakness	Disease duration
	Presence of rash/calcinosis	Gender
	Nailfold capillaroscopy changes	Race/ethnicity
	Joint involvement	Income level
	Current use of steroids	CMAS score
		Gastrointestinal/Cardiac involvement
		Pain score
