AEREL(Causality): 记录研究者对于试验治疗关于事件因果关系的观点. ICH E2A和E2B包括NOT RELATED, UNLIKELY RELATED, POSSIBLY RELATED, RELATED. 未来可能会定义控制术语表. AERELNST(Relationship to Non-Study Treatment):描述研究者对于事件是否与除试验药物之外的治疗有关的观点.

2021年11月11日 · AETERM是EDC收集的不良事件名称，那么在实际记录过程中，对于同样的不良事件，却可能有着不同的AETERM，所以使用MedDRA编码很有必要，在后续分析过程中，也是主要采用的编码后的AEBODSYS/AEDECOD进行不良事件的分析。 AE的开始结束日期时间，这类--DTC的变量都需要采用ISO8601的格式，在后续分析中判断TEAE时需要关注这两个变量，特别是AESTDTC，如果刚好和试验用药同一天，最好可以收集 Time，方便与试验用药的 Time 进行 …
For this paper we will discuss two scenarios that we will handle using ADAE design under CDISC guidance, relation of AE to investigational product and changing of toxicity grade over different periods. Let’s consider a case where an AE is marked as related to a drug from previous treatment period.
Three types of collapsible AEs will be discussed. 1) Multiple AEs with same onset date; 2) Multiple AEs with a time contiguous sequence; 3) Overlapping AEs. This paper will introduce the implementation of collapsing and sample SAS codes for each type of collapsible AE records.
The SDTM includes standard variables for only two possible causes, AEREL for relationship to study treatment, and AERELNST for relationship to non-study treatments. There is no doubt we have to map the CRF field from Table 5 to the AEREL variable. However, in studies with comparator treatment or drug-

2022年3月29日 · ae中记录的事件和研究的治疗不一定有因果关系，由研究人员判断相关性并通过aerel记录。 AE 域结构为每个受试者每个事件一条记录。 由申办者定义一个事件。

Concept Maps for Adverse Events with Increasing Levels of Detail
SDTM includes standard variables for only two possible causes, AEREL for study treatment, and AERELNST for non-study treatments. The following concept map is based on BRIDG modeling of this complex situation.
