Relationship between presence of antinuclear antibodies and clinical form of rosacea

Clinical form	Absence of ANA	ANA titer					Presence of ANA
		1 : 160	1 : 320	1 : 640	1 : 1,280	1 : 2,560
ETR (n = 35)	18 (17.8%)	9 (8.9%)	3 (3.0%)	2 (2.0%)	2 (2.0%)	1 (1.0%)	17 (16.8%)
PPR (n = 57)	24 (23.8%)	13 (12.9%)	10 (9.9%)	6 (5.9%)	2 (2.0%)	2 (2.0%)	33 (32.7%)
Other (n = 9)	5 (5.0%)	2 (2.0%)	1 (1.0%)	1 (1.0%)	0 (0.0%)	0 (0.00%)	4 (4.0%)

ETR – erythematotelangiectatic rosacea, PPR – papulopustular rosacea
