An abbreviation (ABB) in a journal article (JA) or Grant Application (GA) is rarely worth the words it saves. Every ABB requires cognitive resources (CR) and at my age by the time I'm halfway through a JA or GA I no longer have the CR to remember what your ABB stood for.

New paper! 📜
Most of my work relies on large cohort datasets. But how can we ensure transparency and robust research findings using such data?
Here, we present a case study of reproducible practices in epi (with MoBa) and a practical example showing how these practices can be applied.
