目的验证脑动脉硬化症计量诊断判别函数式的可重复性。方法在北京中医药大学东直门医院神经内科病房进行了双盲前瞻性检验,把前瞻检验结果与脑动脉硬化症计量诊断判别函数式诊断结果进行对比评价。结果该函数式的诊断效能有比较好的可重复性,其灵敏度、特异度、误诊率和漏诊率都处于相似水平(P>0.05)。结论该函数式具有一定的推广使用价值。
Objective To verify the reproducibility of the discriminant function formula for the measurement of cerebral arteriosclerosis. Methods A double-blind prospective test was performed in neurology ward of Dongzhimen Hospital of Beijing University of Chinese Medicine. The prospective test results were compared with the diagnostic diagnostic functions of cerebral arteriosclerosis. Results The diagnostic performance of this functional formula was good and reproducible. The sensitivity, specificity, misdiagnosis rate and missed diagnosis rate were all similar (P> 0.05). Conclusion The formula has some promotion and use value.
