Statistical Analysis in Clinical Trials Using the Study Data Tabulation Model (SDTM) and the Analysis Dataset Model (ADaM): Effects, Obstacles, and Solutions

Abstract

Proper statistical analysis is the most important thing in clinical trials if a person wants to come to accurate conclusions and make smart decisions about the safety and effectiveness of new medical interventions. The utilization of the Study Data Tabulation Model (SDTM) and the Analysis Dataset Model (ADaM) is imperative in facilitating this process. The Study Data Tabulation Model (SDTM) is a universally accepted and standardized framework utilized to structure and display data obtained from clinical trials. The utilization of a consistent structure for data representation facilitates the seamless integration and analysis of data derived from various studies. The Study Data Tabulation Model (SDTM) categorizes data into various domains, including but not limited to demographics, adverse events, and laboratory measurements. Variables within each domain are defined and coded using specific controlled terminology, ensuring consistency across different studies. The implementation of a standardized data structure facilitates the accessibility, comprehension, and analysis of data for statisticians, thereby mitigating the potential for errors and augmenting the overall quality of the statistical analysis. In contrast, the Analysis Dataset Model (ADaM) serves as a complementary framework to SDTM, with its primary objective being the preparation of datasets specifically tailored for statistical analysis. The main focus of the study is to examine statistical Analysis in Clinical Trials Using the Study Data Tabulation Model (SDTM) and the Analysis Dataset Model (ADaM). In addition, the study also efficiency and Time-Saving and impact on Data Quality.
