Fig. 3From: Plasma metabolomic profile in orthostatic intolerance children with high levels of plasma homocysteineKEGG enrichment pathway diagram. Bubble size represents the influence factor of the pathway. It increases with the influence factor. Bubble color represents the negative common logarithm of P value (− log10 P value). The color becomes deeper as the P value descends, indicating higher pathway significance level. Rich factor represents the ratio of the number of differential metabolites annotated in the pathwayBack to article page
