Cerebral Aneurysms and Subarachnoid Hemorrhage (JAN 31 – MAR 17, 2017) and
Sports-Related Concussion (JAN 31 – MAR 3, 2017)
A data element which is commonly collected in clinical research studies but whose relevance depends upon the study design (i.e., clinical trial, cohort study, etc.) or type of research involved.
Examples of Supplemental CDEs are the Epilepsy CDEs related to electroencephalogram
(EEG) that are only relevant to epilepsy studies that use EEG for diagnostic purposes
and the Stroke CDEs related to administration of Tissue Plasminogen Activator (tPA) that
are relevant to acute ischemic stroke studies but not relevant to intracerebral
hemorrhage (ICH) studies.
