1·The authors admit to some weaknesses of the study: a large dropout rate, lack of randomization, and a large average BMI (roughly 50).
作者承认本研究存在一些缺点：脱落率较高，缺乏随机化平均BMI较高(约50)。
2·Good randomization is relatively difficult to achieve when working with bundles of trees which cannot be shuffled as can CARDS.
好的随机化是比较难以获得成功的，要把一捆捆的苗木混合，不象洗纸牌那样容易。
3·Unfortunately the 32-bit address space is pretty tight, leaving little room for randomization and hampering its effectiveness.
不幸的是，32位地址空间是非常紧张，留下一点空间随机化，妨碍了其有效性。
4·Thus address space randomization has become popular.
因此，地址空间随机化已经成为流行。
5·In the rst year after randomization, 17 of the 66 patients (26%) assigned to non-operative treatment underwent surgery while 1 patient assigned to surgery refused and was treated nonoperatively.
在随机化后的第一年内，66 例安排进行非手术治疗的患者中，17 例（26%）患者进行了手术治疗，同时也有 1 例分配到手术组 的患者拒绝手术也进行了非手术治疗。
1·DESIGN: Prospective study with complete randomization.
设计：完全随机分组的前瞻性研究。
2·Platelet function was performed at three time points: at baseline, 14 days after randomization, and 14 days after treatment cross-over.
血小板功能在三个时间点：在基线，随机分组后14天，14天治疗后交叉进行。
3·Methods: Divided the rats into treatment group, model group, sham operation group and normal group by sortition randomization method.
实验方法：将大鼠用抽签法随机分组，分为治疗组、模型组、假手术组和正常对照组。
1·Third, selection bias might be a concern as an earthquake may not be a perfect instrument for randomization.
第三，应该注意到选择的偏差，因为地震可能不是一个随机选择的完美工具。
