The CDISC eCRF Portal (available at https://www.cdisc.org/kb/ecrf) is a platform from which to download standard CRFs including metadata standardized per ODM-XML. All example CRFs in Examples Section 3.3, Product Impact on Individual Health, may be downloaded in ODM-XML format ODMformat and loaded into applicable electronic data capture (EDC) tools.
