这是最重要的终点，以及为最小程度受制于研究者偏倚的一个。
It is the most important endpoint and the one that is least subject to investigator bias.
例如，对高度主观性的结果如疼痛，评价者可决定仅纳入对受试者实施盲法以防止实施偏倚的研究。
For example, for highly subjective outcomes such as pain, reviewers may decide to include only studies that prevent 'performance bias' by blinding participants.
评价者可以选择只纳入随机对照试验来尽可能避免偏倚，但这种方式并不能同时保证文献的相关性甚至会漏掉一些高相关性的文献。
In order to minimise bias, reviewers may choose to include only randomised controlled trials (RCTs) in their reviews. While this approach minimises bias it may not always ensure relevance.
另一方面，风险管理者的偏倚使其更青睐风险评价的特定结果。
On the other hand, risk managers have biases that cause them to prefer certain outcomes to risk assessments apriori.
目的为避免选择和发表偏倚，系统评价者应采用多种查询技术，并尽力获得未发表的研究。
Primary objective to avoid selection and publication bias, systematic reviewers should employ a broad range of search techniques and make efforts to locate unpublished studies.
为了防止偏倚，实验者和受试者都不能知道吃了什么。
To guard against bias, neither the experimenters nor the test subjects should know who gets which.
同时由两位评价者分别对纳入研究进行数据提取及偏倚评估。
Duplicate data extraction and assessment of risk of bias in included studies was performed.
有时，这样做能增加数据的可用性，尽管分析者应意识到报告偏倚的可能性。
Sometimes it might be chosen to maximise the data available, although reviewers should be aware of the possibility of reporting biases;
