Identification of Microbial and Proteomic Biomarkers in Early Childhood Caries

Figure 8

Relative importance of proteomic profile peaks for classifying caries-active and caries-free samples using the random forest model. The mass-to-charge (𝑚/𝑧) positions of 25 most important peaks are listed (𝑦 axis), and the shaded bars display their importance. 𝑚/𝑧 positions are given in Daltons. Note that the relative importance of the peak position for multivariate classifier may differ from its individual (univariate) importance (see Figure 6).
