Table 2

Methylation status of miR-124a in synovial tissues of RA and OA*.

Gene	Methylation frequency			𝑃 value
	RA	OA	C	RA versus OA	RA versus C
miR-124-a1	71.4%	16.7%	0	0.07	0.08
miR-124-a2	71.4%	16.7%	0	0.07	0.08
miR-124-a3	57.1%	0	0	0.05	0.17
All three loci	57.1%	0	0	0.05	0.17

∗RA: rheumatoid arthritis; OA: osteoarthritis; C: healthy control.
