Infogram and classification score. (A) Infogram of 1,058 genes that made the least classification errors by LOOCV. The expression levels for each gene were normalized to the geometric mean of all the samples for each gene. Increased genes are shown in progressively brighter shades of yellow, and decreased genes are shown in progressively darker shades of blue. Genes shown in gray are not different between the groups. The genes were ranked according to their significance level. (B) Classification score of every sample in the dataset. Samples below the zero line were considered as usual interstitial pneumonia. Samples above the separation line were classified as HP. Note that only one HP sample was misclassified. NSIP = nonspecific interstitial pneumonia.
