  1. This positive predictive value of 78. 5 % leads the researchers to estimate that if 5 patients with multinodular goiter exhibited the delayed washout pattern on dce - mri, 4 will probably have malignant lesions in the thyroid gland

    通過78 . 5的陽性率使研究者們聲稱，如果5位多發甲狀腺節結具有造影增強的延後消退的影像，那麼其中的4位在甲狀腺中有惡性的病理變化。
  2. Ssg - cp had sensitivity of 85 %, specificity of 94 %, predictive value of the positive test 93 % and predictive value of the negative test 89 %

    超聲晶氧造影診斷輸卵管阻塞的敏感性為85 % ，特異性為94 % ，陽性預測值為93 % ，陰性預測值為89 % ，兩者診斷的符合率為93 % 。
  3. Tail length, tail moment, tail dna percentage, and correction rate were compared between the improved software and the original one, and epidemiological indices for the improved software were also calculated and analyzed, including sensitivity, specificity, youden index, crude agreement, adjusted agreement, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio. results the improved software can correctly analyze most of the images to which the original one cannot give right results

    比較改進前後的尾長、尾矩、尾dna百分含量上的差異、改進前後分析正確率差異、以及改進后的軟體以不同dna損傷級別為截斷值判定陽性結果的靈敏度、特異度、 youden指數、粗一致性、調整一致性、陽性預測值、陰性預測值、陽性似然比和陰性似然比。
  4. The predictive value of heart rate variability is independent of other noninvasive measures commonly used to predict prognosis of cardiac diseases, low left ventricular ejection fraction, and so on. like other risk predictors, measures of heart rate variability have modest positive predictive accuracy when used alone. however, combining measures of heart rate variability with other risk predictors yields a positive predictive accuracy of about 50 %

    心率變異性的預測價值獨立於其他非創傷性預測心臟疾病預后指標（降低的左心室射血分數，頻發重復性室性心律失常等） ，在單獨應用時陽性預報率較低，但與其他指標聯合應用，陽性預報率可達50 。
  5. Positive predictive value

    陽性預測值
  6. More positive results were found, however, leading to a lower positive predictive value

    液基細胞學檢測敏感性較高，因由較高假陽性率，導致陽性預測價值較低。
  7. Hence, the negative predictive value of this method was 58. 3 %, the researchers report, although the positive predictive value was 100 %

    這個方法的假陰性率達到58 . 3 ，盡管陽性的診斷結果的準確率是100的，研究者們報道說。
