Fig. 11. Map of lipid metabolism pathways mainly related to DR. The blue box is the name of the main pathway; the orange box is the biomarker we identified; and the gray box is the important upstream substance associated with the identified biomarker in the pathway; the changes in the intensity of biomarkers in the control group (yellow) and model group (purple) in the KLX intervention group (green) are indicated next to the histogram; the blue arrows indicate the mutual relationship between the substances.
