In tests for pironoma, a serious disease, a false positive result indicates that people have pironoma when, in fact, they do not; a false negative result indicates that people do not have pironoma when, in fact, they do. To detect pironoma most accurately, physicians should use the laboratory test that has the lowest proportion of false positive results.
这个lowest proportion of false positive results到底是指什么呢?我明白肯定是要用false positive的结果,但是这个lowest proportion把我彻底弄混了,到底这个里比例是指的什么?我想来想去都没理出个所以然,晕了,麻烦大家给我好好讲讲 |
