CircRNA expression profile in RA patients, and healthy controls. CircRNA expression was determined by microarray analysis in four RA patients, and four healthy controls. a CircRNA Box-Plot. After normalization, the CircRNA data distribution in 8 samples is uniform, and the symmetry is good, and the position of the overall data is approximately on the same horizontal line, and the fluorescent signal strength is approximately consistent, and the next treatment can be performed. b CircRNA Scatter-Plot. Parts above the first green line and below the third green line represent circRNA with difference multiple greater than 1.5, and parts between them represent circular RNA with no difference in expression
