Poster for Society for Clinical Trials annual meeting in Boston, MA Abstract Randomization methods generally are designed to be both unpredictable and balanced between treatment allocations overall and within strata. However, when planning studies, little consideration is given to measuring these characteristics, nor are they examined jointly, and published comparisons between methods often use incompatible metrics and simulation assumptions. Furthermore, for purposes of real-world planning, such simulations often make unrealistic assumptions (e.g., equal sized strata), and summary statistics give limited information. ]]>
