【摘要】 本文对124例初孕妇自孕20～32周进行了295次等量握拳运动试验(IET),并同时作翻转试验(ROT)。结果提示:IET预测的阳性符合率为71.43％(15/21),阴性符合率为90.29％(91/103)。而ROT的阳性符合率和阴性符合率分别是70.59％(12/17)和87.85％(94/107)。两种方法比较,IET的预测效果略优于ROT,但无统计学意义(P>0.05),说明两者均有较高的特异性和敏感性。若将两种方法联合预测,则能进一步提高预测效果。更多还原

【Abstract】 One hundred and twenty-four normotensive primigravidae underwent an isometric handgrip exercise test (IET) and a simultaneous roll over test (ROT) between 20 and 32 weeks of gestation. Of the 21 patients having a positive IET result, fifteen (71.43%) developed hypertention. Of the 103 patients who had negative results, ninety--one (90.29%) remained normotensive throughout pregnancy. The true positive rate and true negative rate of ROT in he same group is 0.59% (12/17)and 87.85% (94/107) respectively. In comparison with ROT, IET has a slightly better predictive value. However, the differece was not statistically sgnificant. Both IET and ROT have good specificity and sensitivity; When combined the predictive value may be further improved.更多还原
