Noem mij niet blond,
noem mij niet gesluierd
ik ben het licht
dat door beiden heen schijnt.
Je kunt mij niet scheiden
in goed of kwaad,
want liefde
kent geen grenzen
en angst
is geen waarheid.
We zijn geen twee gezichten

The REDCap Revolution: How a Clinical Data Management Tool Empowered Global Research Communities
Twenty years ago, handling clinical data was a tedious, unorganized process—until REDCap, a “big dumb container,” put in seamless guardrails.

Happy Birthday John Snow!!!
Small note: he didn't use disease mapping to 'determine the source' of the London cholera outbreak in 1854. He suspected the Broad Street pump immediately. His map was created to try and convince people that cholera spread through water, a radical argument at the time.

Happy (early) Birthday to the father of Field Epidemiology! John Snow, who turns 212 on March 15th, is legendary for using disease mapping to determine the source of the London cholera outbreak in 1854. #JohnSnow #Epidemiology

The 'new regression models' can be described and interpreted very easily, they even allow statistical inference, they perform just as well as good old machine learning and they no longer consume any energy once they have been developed and written down as a formula on a piece of paper!

Academics, let's make 2025 the year where we are more explicit and honest about our causal aims and interpretations
Using, for instance, the terms "risk factor" or "associated with a decrease in" is not a clever way to avoid the issue

I am running my statistical rethinking course again starting in January. But this time just for Leipzig locals, so I can work with a smaller group this year and track individual progress better. I think that will help me tune the material, espeically homework, better. Materials still open however.
