查询词典 randomized

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。

The variability in the populations studied (e.g., combat, noncombat, recent traumatic experiences) leaves additional unanswered questions that must be addressed in large, randomized, controlled trials.

研究人群中的可变因素（如战斗的、非战斗的、新近的创伤体验）使得一些额外问题悬而未决，必需由大规模的随机对照临床试验加以解决。

The 24-week study randomized women who had undergone hysterectomy and bilateral oopherectomy at least six months before to 300 g testosterone administered by testosterone transdermal patch twice a week or placebo. The primary end point was change in total sexual activity as recorded in a sexual activity log. A secondary end point was score on the Profile of Female Sexual Function, an instrument that records seven domains of sexual function, including number of sexual activities, both intercourse and nonintercourse, and orgasm. Incidence of personal distress disorder was also evaluated.

一项为期24周的研究，研究人员随机给予至少六个月前经子宫切除或双侧卵巢切除的妇女，每周两次300毫克经由皮肤渗透的睪固酮或安慰剂，初步的目的是想透过sexual activity log的纪录，以了解整体的性能力；第二项目的是替妇女性功能测影Profile of Female Sexual Function计分，一项仪器纪录了七项主要的性功能指数，包括性行为次数、交往与非交往数目与高潮次数；个人忧虑症发生机率同时也包含在评估当中。
