Principal component analysis (PCA) (A) and partial least squares discriminant analysis (PLS-DA) (B) score plots for candidate plasma markers in diabetic macular edema (DME) and non-DME subjects analyzed by GC–TOF–MS in discovery cohort. Black filled circle—non-DME group, red filled circle—DME group.
