Serum miR-222 levels
High (equal or more higher than median)	0.72	(0.38-1.37)	0.367
Low (less than median)	1.00
Serum miR-148 levels
High (equal or more higher than median)	1.00	0.32-1.16	0.613
Low (less than median)	0.61
Serum miR-155 levels
High (equal or more higher than median)	0.75	0.39-1.42	0.099
