TI Methods Speaker Series: It’s about Nothing: Dealing with Missing Data in Clinical Trials

28 Aug 2019 TI Methods Speaker Series: It’s about Nothing: Dealing with Missing Data in Clinical Trials

Missing data, particularly on primary outcomes, presents a dilemma to researchers, not only because it may lead to lower than anticipated sample sizes and statistical power, but more seriously because missing data is often non-random and simply ignoring it can result in seriously biased comparisons.  This talk will review the strategies that have been commonly used to cope with this problem, culminating in the more sophisticated models which impute data essentially using regression-like approaches.  It is important to understand that even these more sophisticated approaches do make assumptions, and the use of statistical software does not obviate the need to think through the particular problem.
