____ Add text on Ejection Fraction and DMD
Measurements such as Cardiac Index (as seen in the example below) and Spirometry are effected by Body Service Area (https://www.ahajournals.org/doi/10.1161/CIRCIMAGING.115.003810). It is important in the DMD population to ensure the height and weight are current for accurate data collection (especially as the participant becomes wheelchair bound). Height and weight are represented in the Vital Signs domain, refer to the SDTMIG v3.4, Section 6.3.13 for more information.
Age plays a role in the assessment analysis. The age would be found in the Demographic domain, refer to the SDTMIG v3.4, Section 5.2. At the point of the study, the age may be collected or referenced.
