Behind the Science

Sonja Kroep

Sonja Kroep is an Associate Director in the Modeling & Meta-Analysis Center of Excellence at OPEN Health. With a strong focus on quantitative evidence synthesis and endpoint surrogacy analysis, she has established herself as an expert in these fields. Additionally, she is specialized in data analysis, with a particular emphasis on statistical models and survival analysis.

Methods for Indirect Treatment Comparisons (ITCs)

Together with the team, Sonja developed the Matching Adjusted Indirect Comparison (MAIC) interactive poster to show the "black box" behind the commonly conducted MAIC analysis.
