Joining the PLOS Biology editorial board

I am happy and honored that I can share that I am going to be part of the PLOS Biology editorial board. PLOS Biology has a special model for their editorial duties, with the core of the work being done by in-house staff editors – all scientist turned professional science communicators/publishers. They are supported by the academic editors – scientists who are active in their field and can help the in-house editors with insight/insider knowledge. I will join the team of academic editors.

When the staff editors asked me to join the editorial board, it quickly became clear that they invited because I might be able to contribute to the Meta-research section in the journal. After all, next to some of my peer review reports I wrote for the journal, I published a paper on missing mice, the idea behind sequential designs in preclinical research, and more recently about the role of exact replication.

Next to the meta-research manuscripts that need evaluation, I am also looking forward to just working with the professional and smart editorial office. The staff editors already teased a bit that a couple of new innovations are coming up. So, next to helping meta-research forward, I am looking forward to help shape and evaluate these experiments in scholarly publishing.

Where Have All the Rodents Gone? The Effects of Attrition in Experimental Research on Cancer and Stroke



We published a new article just in PLOS Biology today, with the title:

“Where Have All the Rodents Gone? The Effects of Attrition in Experimental Research on Cancer and Stroke”

This is a wonderful collaboration between three fields: stats, epi and lab researchers. Combined we took a look at what is called attrition in the preclinical labs, that is the loss of data in animal experiments. This could be because the animal died before the needed data could be obtained, or just because a measurement failed. This loss of data can be translated to the concept of loss to follow-up in epidemiological cohort studies, and from this field we know that this could lead to substantial loss of statistical power and perhaps even bias.

But it was unknown to what extent this also was a problem in preclinical research, so we did two things. We looked at how often papers indicated there was attrition (with an alarming number of papers that did not provide the data for us to establish whether there was attrition), and we did some simulation what happens if there is attrition in various scenarios. The results paint a clear picture: the loss of power but also the bias is substantial. The degree of these is of course dependent on the scenario of attrition, but the message of the paper is clear: we should be aware of the problems that come with attrition and that reporting on attrition is the first step in minimising this problem.

A nice thing about this paper is that coincides with the start of a new research section in the PLOS galaxy, being “meta-research”, a collection of papers that all focus on how science works, behaves, and can or even should be improved. I can only welcome this, as more projects on this topic are in our pipeline!

The article can be found on pubmed and my mendeley profile.

Update 6.1.16: WOW what a media attention for this one. Interviews with outlets from UK, US, Germany, Switzerland, Argentina, France, Australia etc, German Radio, the dutch Volkskrant, and a video on More via the corresponding altmetrics page . Also interesting is the post by UD, the lead in this project and chief of the CSB,  on his own blog “To infinity, and beyond!”


New article published – Conducting your own research: a revised recipe for a clinical research training project

2015-06-07 15_38_24-Mendeley Desktop

A quick update on a new article that was published on friday in the NTVG. This article with the title

“Conducting your own research: a revised recipe for a clinical research training project”

– gives a couple of suggestions for young clinicians/researchers on how they should organise their epidemiological research projects. This paper was written to commemorate the retirement of prof JvdB, who wrote the original article back in 1989. I am quite grew quite fond of this article, as it combines insights from 25 years back as well as quite recent insights (e.g. STROBE and cie Schuyt and resulted in a article that will help young research to rethink how they plan and execute their own research project.

There are 5 key suggestions that form the backbone of this article i.e. limit the research question, conduct a pilot study, write the article before you collect the data, streamline the research process and be accountable. As the article is in Dutch only at this moment, I will work on an English version. First drafts of this ms, each discussing each of the 5 recommendations might appear on this website. And how about a German version?

Anyway, it has to be mentioned that if it not was for JvdB, this article would have never come to light. Not only because he wrote the original, but mostly because he is one of the most inspiring teachers of epidemiology.
