Consecutive M/Z is the numerical order of the M/Z value between 1 and 15,154. The M/Z values were sorted by p-values and the lowest 100 were arbitrarily selected. The M/Z values were then binned as described in the text, and the most significant consecutive M/Z score from each of the 12 bins was selected. M/Z values that were selected by the stepwise discriminant analysis are designated a "S" in the Rule 1 column. The Wilcoxon p-values calculated from the training set (used to derive the rule) and calculated from the entire data set are shown in their respective columns.
