Characterization of microbiota in systemic-onset juvenile idiopathic arthritis with different disease severities

Table 1 Clinical characteristics of systemic-onset juvenile idiopathic arthritis patients and healthy subjects

	A-SoJIA	Ina-SoJIA	HS	P-value
Number	17	15	32	-
Age, mean ± SD, yr	10.9 ± 3.3	11.7 ± 2.8	10.3 ± 2.9	NS1
Age range	6 to 15	7.3 to 16	5-16	-
Male, n (%)	9 (52.9)	7 (46.7)	18 (56.3)	NS2
Disease duration, mean ± SD, mo	58.4 (46.9)	48.5 (28)	-	NS3
ESR (mm/h)	33 ± 38	4 ± 4	-	P < 0.013
CRP (mg/L)	13.5 ± 58.5	1 ± 3	-	P < 0.013

The P-values were calculated according to

¹ANOVA,

²Pearson chi-square test, and

³Mann-Whitney U test. SoJIA: Systemic-onset juvenile idiopathic arthritis; A-SoJIA: Active SoJIA, Ina-SoJIA: Inactive SoJIA; HS: Healthy subjects; ESR: Erythrocyte sedimentation rate; CRP: C-reactive protein; NS: Not significant.
