SDTM. Ejection Fraction

This example dataset shows the findings associated with a Cardiac Magnetic Resonance Imaging procedure related to ejection fraction. CVDTC is the date of the CMR procedure, CVDY is the study. For the purposes of this example, the participant was enrolled in the study on 20-May-2021 and the study visits were every two months. The CVLNKID variable is used to identify a record to show a relationship between records in separate domains.

Rows 1-8:	Show the baseline CMR ejection fraction measurements for participant 101 at VISIT 1.
Rows 9-16:	Show the CMR ejection fraction measurements for participant 101 at VISIT 6.
