The SDTM examples used as the source data are from Section 2.1, Basic Systolic Function. The ADSL draws from the DM dataset, which shows 4 subjects. The CV dataset shows two visits for the first subject, DMD-EF-01-101. It contains 16 rows, 1-8 for visit 1 and 9-16 for visit 6. Of these rows, the CVTESTCD = "LVEF_C" and CVTESTCD = "RVEF_C" representing the Ventricular Ejection Fraction, Calculated (%) for left and right were selected for the analysis. The LB dataset test where LBTESTCD = "BNPPRONT" was used to add the value of BNPPRONT to compute the percent change over time, and then was added as a potential covariate in each row for the last analysis. 

Example Analysis Datasets

...

This is a simplified example ADSL dataset; it is expected that the Foundational standards are followed to include all the core variablesADaMIG is referenced. Analysis age (AAGE) was computed included to provide age with more precision.   The Body Surface Area (BSA) at screening is named BSASC as per the ADAMIG v1.2.   There are many possible calculations for BSA. For ; for this example, the Du Bois method was used (footnoteref: https://www.calculator.net/body-surface-area-calculator.html).

ADCVNTP Analysis Dataset

In this example, columns for derived variables BASE, CHG, PCHG and CHGCAT1 have been added to facilitate analyses of the efficacy endpoints. Specifically, example demographic data for ADSL were created for an 8 year old male. Also, a custom variable for BSA at baseline (BSABL), and an example of a stratification variable for subjects with was added from ADSL.
