查询词典 randomized decision function

Methods Sixty-seven cases of adult patients undergoing valves replacement were randomized into modified ultrafiltration group (n=33) and control group (n=34). Blood gas parameter such as PO2, PCO2 were measured at pre-cardiopulmonary bypass, end CPB, and post MUF (or 20 min post CPB in control group). Ventilatory support time, usage time and amount of vasoactive drug and ejection fraction of left ventricular were also measured in the early period of operation.

Methods A total of 6 352 students were chosen by multi stage randomized sampling, the information of the students aged 7-8 were collected by face to face interview, students aged 9-18 by self administered questionnaire. Results The incidence rate of injury was 48.0%, and there were 30.4% of the students reporting had committed injury. Every injury case had 1.58 injuries during one year averagely.

Methods A randomized,double-blind,double-simulant,parallel-controlled,multicentric study was carried out in 207 patients with bladder overactivity,patients received either tolterodine (2 mg twice daily)or oxybutynin (5 mg twice daily).

采用随机、双盲、双模拟、平行对照的方法对207例膀胱过度活动症患者进行托特罗定与奥昔布宁的对比研究，服药方法每日2次，每次托特罗定2mg或奥昔布宁5mg。

P×P and P were two major non-Bayesian algorithms. 6 Less than 25% of the participants used frequency. In those who got other results except P , much more people used probability. Experiment 2 had a randomized multigroup posttest design. There was only one factor named implied condition which had five levels: not imply, imply P, imply addition, imply division and imply all. The results showed that: 1 All the implied conditions significantly improved the participants' performance. When under the condition of implying division, the participants derived the best results. 2 31.9% of the participants got correct answer, 73% of who used frequency to rewrite the information. 3 78% of the participants could apply one or several of the four concepts: probability of "not the event", multiplication rule, addition rule and condition probability.

结果表明：1 被试的估计受问题内容的影响，权威型问题情境容易使被试高估，非权威型问题情境使被试的高估现象大大减少；数据结构和提问形式对被试估计不产生影响。2 有近5%的被试能正确估计P，其中 73%使用频数对信息进行再表征。3 贝叶斯推理中各分步骤的困难程度由低到高分别是：乘法、P、加法、除法。4 有50%的被试能运用对立事件概率、概率乘法、概率加法、条件概率这四个概念中的一种或者几种。5 使用最多的两种非贝叶斯算法是P×P和P。6 不到25%的被试使用频数；求得除P以外各类结果的被试中，使用概率的人数远多于使用频数的。
