Interrater reliability^* of Localized Scleroderma Skin Severity Index (LoSSI) and its domains.

Examiners**	Surface Area	Erythema†	Skin Thickness	LoSSI
All examiners (n = 14)	0.35 (0.25, 0.49)	0.71 (0.58, 0.84)	0.70 (0.60, 0.80)	0.80 (0.68, 0.91)
Senior examiners (n = 5)	0.44 (0.29, 0.60)	0.68 (0.50, 0.84)	0.74 (0.62, 0.83)	0.83 (0.68, 0.93)
Junior examiners (n = 5)	0.38 (0.24, 0.55)	0.73 (0.57, 0.86)	0.72 (0.60, 0.82)	0.82 (0.67, 0.93)
Clinical fellows (n = 4)	0.24 (0.10, 0.42)	0.76 (0.58, 0.88)	0.65 (0.51, 0.78)	0.85 (0.68, 0.94)

^*Assessed by intraclass correlation coefficient (ICC) and reported as ICC (95% confidence interval).

^**Senior examiners have > 10 years, junior examiners ≤ 10 years in practice.

^†Erythema score reliability was assessed using 20 photographs of skin lesions.
