Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

International Activities

Project Lead

In collaboration with the ZIKV IPD Consortium, investigators at Utrecht University will lead the development of the detailed analysis plan and draft code to conduct the ZIKV IPD meta-analysis.

Project details...

This project aims to develop innovative approaches to the synthesis and analysis of clinical-epidemiological (CE) and high dimensional laboratory (HDL) data, and modify governance models for cloud-based repositories elaborated by and for scientists in high-income countries to meet the specific challenges of synthesizing CE and HDL data and sharing data across international cohorts and with the Open Science community.

Project details...

This project aims to develop a statistical framework that utilizes big datasets to identify and account for heterogeneity in predictor effects. Hereto, existing meta-analysis methods will be improved upon and a new penalization algorithm will be derived to enhance the estimation and inclusion of relevant predictors during the adaptation and development of prediction models. Ultimately, this will reduce the need for further validation and adaptation of prediction models.
