IL-17 Median and IQR (pg/mL) in Synovial Fluid from RA and OA Patients and Healthy Controls

Biomarker (units pg/mL)	RA (N=5)	OA (N=5)	Healthy controls (N=5)
IL-17A	0.07 (0.07, 3.1)	0.045 (0.043, 0.07)	0.07 (0.07, 0.07)
IL-17F	130* (120, 2000)	95* (13, 450)	1.6 (1.6, 2)
IL-17AF	13 (8.8, 41)	6 (1.5, 8.8)	0.77 (0.77, 0.84)

^*IL-17F was significantly higher in RA compared to healthy controls (p=0.016) and in OA compared to healthy controls (p=0.048). No other differences between groups were significant
