0 a result of a scientific test that appears to show something exists or is present, when this is not correct: --
The anthrax test is unreliable because it produces too many false positives.
This potentially interferes with the detection of doublepositive target cells and leads to false positive results in the cytotoxic assay.
At the same time, the strategy also reduces the number of multiple test and thus false positive results.
Neurodevelopmental outcome was better in male fetuses with an atrium of < 12mm, probably due to the higher false positive rate.
Lower thresholds result in higher powers but also suffer from higher false positive rates.
As a measure of accuracy, we calculated the difference in the false positive rate between procedures.
Indeed, theoretical thresholds could lead to an increase in the false positive rate.
If the 28 growth restricted fetuses had been included, the false positive rate would have been even higher.
False positive rates were also published and varied significantly.
