PCA statistical analysis model of periapical periodontitis using UPLC-QTOF/MS. The abscissa represents the first principal component and the ordinate represents the second principal component. A Positive ion mode, B negative ion mode. The red, green, and purple scatters represent the metabolic profiles of periapical periodontitis as grade I, grade II, and grade III, respectively. Light blue scatters represent the QC samples. Each scatters represents a sample, and the closer the scatter is, the higher the similarity of the principal components of the samples exists
