您好,

在项目中经常会出现Permissible Variable所有值都是空值的情况。根据SDTM IG,“If a study includes a data item that would be represented in a Permissible variable, then that variable must be included in the SDTM dataset, even if null.”  。看上去这种Permissible Variable所有值都是空值的情况也是被IG所接受的。那么规则SD1078 Permissible variable with missing value for all records是否还有必要核查?

我的猜想是,Pinnacle 21 认为该变量可能是冗余的,保留它会增加数据处理难度,还可能掩盖数据收集问题。对于未在 CRF 出现的Permissible变量,放进 SDTM 数据集会破坏数据来源的可追溯性,SDTM 数据集应反映实际收集的数据,随意添加这类变量会导致数据混乱。  请问我的观点是否有误?

你好, 

通过参考 Define.xml“Has No Data”属性增强 SD1078 检查将于今年晚些时候推出。

亲切的问候
