Measuring LVEF regularly can show the rate of decline in left ventricle function for a patient with DMD. Therefore, it was selected as an endpoint for this example to measure whether a course of therapy may slow the progression of heart failure for the patient. The second endpoint chosen, NT-proBNP, is a biomarker that may be used to predict or diagnose heart failure.
This section illustrates example analysis datasets for the following endpoints:
- Percent change in ejection fraction over time (1 year)
- Decline in ejection fraction over time (1 year) grouped by a decline greater than -5.0%
- Percent change in NT-proBNP over time (1 year)
Source Data
The SDTM examples
This section illustrates example analysis datasets for the following endpoints:
- Percent change in ejection fraction over time (1 year)
- Decline in ejection fraction over time (1 year) grouped by a decline greater than 5%
- Percent change in NT-proBNP over time (1 year)
Source Data
The SDTM examples used as the source data are from Section 2.1, Basic Systolic Function. The ADSL draws from the DM dataset. The CV dataset shows two visits for subject DMD-EF-01-101. The records records in the CV dataset for which CVTESTCD = "LVEF_C" and "RVEF_C" were selected for analysis. The records in the LB dataset where LBTESTCD = "BNPPRONT" were used to compute the percent change over time and as a potential covariate.
Example Analysis Datasets
Both SDTM domains are used in one analysis dataset to demonstrate the flexibility of ADaM and to show that the various SDTM domains can be combined into one dataset both as rows and also as covariates.

ADSL
The ADSL contains subject characteristics and covariates that are important for analyses. Stratification variables can be created in the ADSL to subset the data. More than one SDTM dataset may be used as input to the ADSL. This is a simplified example ADSL dataset; the ADaMIG should be referenced for additional variables.
...
- Analysis age (AAGE) was included to provide age with more precision.
- A flag indicating the use of ACE inhibitors (ACEINHFL) was derived is shown with example derivation from the CM dataset.
- Body surface area at screening (BSASC) was derived from the VS dataset using height and weight at the screening visit. There are many possible calculations for BSA; for this example, the Du Bois method was used (ref: https://www.calculator.net/body-surface-area-calculator.html). Note that the .[11] Note that the screening visit and visit 1 occurred at the same time in this example.

ADCVNTP
The ADCVNTP includes tests pertinent to analyses. The records from CV where CVTESTCD = "LVEF_C" and "RVEF_C" and the records from LB where LBTESTCD = "BNPPRONT" were selected. Many lab draws may occur throughout the year, but only those linked to a specific visit were included. By subsetting the LB dataset by LBLNKID not missing, laboratory data that aligns with CV data can be filtered out and sorted using USUBJID and VISIT. If LBLNKID is not available, a windowing strategy could be used to select the laboratory draw closest to that visit for merging with CV, computed in AVISIT.
In this example, variables BASE, CHG, PCHG and CHGCAT1 were used to facilitate analyses of the efficacy endpoints.

ADCVCMR
The ADCVMR is an efficacy analysis dataset with only a few records for more complex modeling of changes in ejection fraction, plus the ProB-type test results. It is an ADaM Basic Data Structure (BDS) dataset, with additional variables added from ADCVNTP.

The dataset can provide multivariate analyses by taking the lab tests of interest (PARAMCD = "BNPPRONT") or other analysis datasets, and and merging variables of interest with the
ADCVNTP ADEFNTP dataset. This summary dataset is created from other ADaM datasets and only variables used in the analysis are kept.
