About Gerard van Breukelen

Gerard van Breukelen, With an exceptional h-index of 65 and a recent h-index of 34 (since 2020), a distinguished researcher at Universiteit Maastricht, specializes in the field of optimal design and sample sizes, multilevel models and mixed regression, causal inference, psychometrics.

His recent articles reflect a diverse array of research interests and contributions to the field:

Laparoscopic versus open hemihepatectomy: the ORANGE II PLUS multicenter randomized controlled trial

Norms for the Dutch Version of the Young Schema Questionnaire–Adolescent in a Clinical Population

Sample size calculation and optimal design for regression-based norming of tests and questionnaires.

Cluster Randomized Trials with a Pretest and Posttest: Equivalence of Three-, Two-and One-Level Analyses, and Sample Size Calculation

E-ReMI: Extended Maximal Interaction Two-mode Clustering

Dealing with missing observations in the outcome and covariates in randomized controlled trials

Best (but oft forgotten) practices: Efficient sample sizes for commonly used trial designs

Sample Size Calculation and Optimal Design for Multivariate Regression-Based Norming
