Statistical Overview for Clinical Trials Basics of Design and Analysis of Controlled Clinical Trials Presented by: Behrang Vali M.S., CDER/OTS/OB/DB3 . Explain the uses, importance, and limitations of early stopping rules in clinical trials. Statistical analyses of BE data are typically based on a statistical model for the logarithm of the BA measures (e.g., AUC and Cmax). 9. Assuming that a clinical trial will produce data that could reveal differences in effects between two or more interventions, statistical analyses are used to determine whether such differences are real or are due to chance. Analysis Guide 50 Trial Data Release 50 16. Evaluate computer output containing the results of statistical procedures and graphics. III. A necessary companion to well-designed clinical trial is its appropriate statistical analysis. TRIAL ADMINISTRATION–HOW INVESTIGATORS/ STAFF WILL BE ... Use qualitative information from patients and clinical staff to revise intervention materials and procedures. Chapters 1-4 concern statistical methods in designing and analyzing data for survival clinical trials, and predicting trial duration. Objective of clinical trials The objective of clinical trials should be expressed clearly and concretely. 3 Statistical Approaches to Analysis of Small ClinicalTrials. Analysis: (1) Data collection and processing (2) Computation of test statistics (3) Preparation of graphics and tables (4) Interpretation of results for the primary investigator The 3 components of a clinical trial conduct, and analyses of clinical and translational research. statistical and clinical inference can be seen: Firm evidence in support of claims requires that the results of the confirmatory trials demonstrate that the investigational product under test has clinical benefits. The confirmatory trials should therefore be sufficient to answer each key clinical question relevant to the efficacy or safety claim 10. Special Thanks to: LaRee Tracy, Mike Welch, Ruthanna Davi, and Janice Derr The subsections below will describe analyses in addition to the descriptive statistics. statistical analysis. The role of statistics in clinical trial design and analysis is acknowledged as essential in that ICH guidance.

The model is a mixed-effects or two-stage linear model. 6.1 Primary outcome The primary analysis will compare intervention groups (water supplementation vs control treatment) on their mean change in fasting plasma glucose between baseline and 12 months using a linear mixed model.
