摘要
目的 :探讨预设和调节疫苗效力可信区间宽度方法在评价疫苗保护效果方法的应用。方法 :应用预设和调节疫苗效力 (VE)可信区间宽度的方法 ,推导出预防试验研究评价 VE所需样本含量的计算公式。结果 :由公式计算的样本含量能使研究者掌握由样本所获得的 VE点估计值接近总体真实值的程度。结论 :该方法能较为准确地判断研究结果的实际意义。
Objective:To explore the death cause of reproductive age women in Rudong County.Methods:Analyzed the death causes of reproductive age women 1423 cases in Rudong county from 1994 to 1998.Rusults:The death rate was 86 26/10 5 and proportion was 7 98% among all the death women.The major death causes were injured.Poisoning and carinoma which occupied 35 28% and 29 86%.Conclusion:Suicide and motor vehicle traffic accident were major causes of poisoning and injured,liver,lung,gastric and mammary cancer were major carcinomas which led the reproductive age women to death.
