Publications and further publicity

Publications

So far, five scientific publications came out of the SAVVY project.

  • Stegherr, Beyersmann, et al. (2021): Statistical analysis plan, presenting the rationale and statistical concept of the empirical study conducted as part of the SAVVY project. The statistical methods are presented in unified notation and examples of their implementation in R and SAS are provided. arxiv | publication
  • Stegherr, Schmoor, Lübbert, et al. (2021): Comparison of estimators via simulations. arxiv | publication
  • Stegherr, Schmoor, Beyersmann, et al. (2021): 1-sample case, compares estimators of AE risk in one treatment arm. arxiv | publication
  • Rufibach et al. (2023): 2-sample case, compares relative risk estimators comparing two treatment arms based on (1) AE probabilities and (2) hazards. arxiv | publication
  • Rufibach et al. (2024): Overview paper, summarizing the above four papers and sketching a roadmap how to move forward with estimation of AE risks. arxiv |

Podcasts

Jan Beyersmann and Kaspar Rufibach have also been interviewed for two effective statistician podcasts discussing SAVVY:
