Combining randomized and non-randomized data to predict heterogeneous effects of competing treatments

Konstantina Chalkou, Tasnim Hamza, Pascal Benkert +7

Some patients benefit from a treatment while others may do so less or do not benefit at all. We have previously developed a two-stage network meta-regression prediction model that…

A two-stage prediction model for heterogeneous effects of many treatment options: application to drugs for Multiple Sclerosis

Konstantina Chalkou, Ewout Steyerberg, Matthias Egger +3

Treatment effects vary across different patients and estimation of this variability is important for clinical decisions. The aim is to develop a model to estimate the benefit of al…
