Jeg ble nylig intervjuet av Aftenposten om vår nye artikkel om symptomer på unngående restriktiv spiseforstyrrelse (ARFID)
Ny studie: Nesten hvert fjerde barn viser symptomer på spiseforstyrrelser
– For et mindretall er dette ikke vanlig kresenhet, men en spiseforstyrrelse som kan ha negative konsekvenser for både fysisk og psykisk utvikling, sier forsker Ludvig Daae Bjørndal.

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.

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.
