Comparison of Combined Arteritis Damage Scores Between Takayasu Arteritis and Giant Cell Arteritis

	Total, n = 51	TAK, n = 24	GCA, n = 27	P
CARDS before treatment, median (IQR)	0 (0-1.6)	1.2 (0.3-1.9)	0 (0-0.3)	.001
CARDS after treatment, median (IQR)	0.6 (0-1.6)	1.2 (0-2.2)	0 (0-1.2)	.018

Data were analysed using the Mann–Whitney U-test. The P values are calculated for the differences between TAK and GCA. CARDS is computed as follows: (number of vessels with <50% stenosis × 0.6) + (number of vessels with ≥50% stenosis × 1.2) + (number of vessels with occlusion × 1.6) + (number of vessels with dilatation or aneurysm × 0.8).
