NOTE. Classification prediction results for 693 prospectively collected acute leukemia samples from stage II. Gold standard classes are given in rows C1/GS to C14/GS; the prediction results are displayed for each sample in columns C1 to C14.

Abbreviations: IDC, indeterminable calls; CR, call rate [(No. of specimens–IDC)/No. of specimens]; GS, gold standard.

^*Values indicate correct prediction results.

^†Values represent misclassifications for each class.
