The upper half of the table describes the results when tubes 1 to 5 of the B-CLPD panel are used; the bottom half tabulates the results from the same validation set cases using tubes 1 and 2 of the B-CLPD panel only. Mean plus SD of sensitivity, specificity, PPV, and NPV were calculated by bootstrapping.
NC, not classified, NPV, negative predictive value; PPV, positive predictive value.
