The confusion matrices show the numbers of subjects correctly and incorrectly classified for each iteration of the classification. Step 1: 11 genes diagnostically differentiating BD + SZ from NC. Step 2: 5 genes diagnostically differentiating SZ from NC. Step 3: 4 genes diagnostically differentiating BD from NC. Step 4: 3 genes diagnostically differentiating SZ from BD. Final call: summary of the step 1, 2, 3, and 4 classifications. BD, bipolar disorder; SZ, schizophrenia; NC, normal control.
