There is also no discussion concerning the falsepositive rate. In the best case, the misidentifications of the two models would coincide, and the falsepositive rate would be max(0.03, 0.068) = 0.068. Decreased falsepositive responses indicates improvement from baseline to retest. The greatest concern is probably the high likely proportion of falsepositive results. The variability of errors and falsepositive or negative responses is too small to differentiate the 5th and 95th percentiles. Matching the cutoffs for all three events does, of course, reduce the falsepositive error; but the price is to increase the false negative error. Falsepositive rates were also published and varied significantly. If the 28 growth restricted fetuses had been included, the falsepositive rate would have been even higher. Indeed, theoretical thresholds could lead to an increase in the falsepositive rate. As a measure of accuracy, we calculated the difference in the falsepositive rate between procedures. Lower thresholds result in higher powers but also suffer from higher falsepositive rates. Neurodevelopmental outcome was better in male fetuses with an atrium of < 12mm, probably due to the higher falsepositive rate. At the same time, the strategy also reduces the number of multiple test and thus falsepositive results. This potentially interferes with the detection of doublepositive target cells and leads to falsepositive results in the cytotoxic assay.
