在科研工作中,检测数据应力求准确(现测指标的真实性)精密(观测指标所能选到的精度),准确性尤为重要、准确性取决于检测方法的敏感性(对病人的检出率)、特异性(对非病人的鉴别率)和重现性(相同条件下的一致程度)这3个因素。了解其间的关系,有助于评价检测方法和科研成果,有利于提高防治疾病的质量。应用配对四格表评价检测方法的有关统计指标:
In scientific research, the accuracy of the test data should be accurate (the accuracy of the measured index), the accuracy (the accuracy of the index can be selected), the accuracy depends on the sensitivity of the detection method (the detection of the patient Rate), specificity (non-patient discrimination) and reproducibility (same degree of agreement under the same conditions) these three factors. Understanding of the relationship between the help to evaluate test methods and scientific research, help to improve the quality of disease prevention. Application paired four grid table evaluation method of the relevant statistical indicators:
