Figure 2 Expression differences in SNHG5 between the DME and refractory DME groups. RT-qPCR analysis of the differences in the expression of SNHG5 in the aqueous humor (A) and serum (B) of patients. * P<0.05; DME – diabetic macular edema; RT-qPCR – quantitative reverse transcription polymerase chain reaction; AH – aqueous humor. Photoshop software (version 21.2.4; Adobe, Inc; San Jose, USA) was used for creation of the figure.
