In the design of clinical studies, definitions of the target parameters (end points) to be measured are required. These serve as a basis for the selection of suitable statistical methods and thus the calculation of necessary sample sizes. The choice of the target parameters suitable for the respective question is based on relevant previous studies and on any available meta-analyses. The freedom of choice of target parameters is thus constrained by boundary conditions.

We consider the standardization of target parameters as necessary for a number of reasons, notably the comparability of different studies. So far, great heterogeneity has been observed in terms of target parameter choice (e.g., [10]). Dependent on the respective hypothesis, target parameter selection also has a significant impact on sample size planning in clinical trials [13].

As a result of an open process within the German Working Group for Evoked Response Audiometry (AG-ERA) of the Working Group of...
