112. In test 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 piroma 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. Which of the following, if true, gives the most support to the recommendation above? 答案是(E) All laboratory tests to detect pironoma have the same proportion of false negative results. 不懂答案為什麼是(E) 請問有人可以為我解答一下嗎? 感謝:) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.115.231.168

我覺得E有"比較基礎相同"的含意,每個實驗測試出現偽陰性

的比例相同,可以support主結論中"使用偽陽性比例最低的

實驗測試-->"最有效"檢驗pironoma"

也就是說把"false positive"視為考慮有效性的單一變數
