My favourite moment of @nataliaortega.bsky.social's talk was when she said you can find a nutrition meta analysis to support whatever argument you want to make about diet and health!

Nice clear presentation of commonplace meta-analysis failure mode: Pooling coefficients that mean different things, because original models had different adjustment sets. A coefficient gets its meaning from the whole model, not just from the predictor variable it multiplies.

Meta-analyses in nutrition may pool estimates for completely incomparable effects without realising it, just because of whether/how energy intake is adjusted. @nataliaortega.bsky.social will explain why, share results from a meta-scientific review & offer recommendations for ways forward 👇

@societyforepi.bsky.social members, don't miss our epic symposium on meta-scientific reviews Feb 9th, 3pm ET/8pm GMT Featuring: myself 💁🏼‍♀️ Peter Tennant @pwgtennant.bsky.social Camila Olarte Parra Noah Haber @whaleactually.com Harrison Hansford Natalia Ortega Herrero @nataliaortega.bsky.social

Meta-analyses of dietary exposures must consider energy adjustment (preprint) 🧵 arxiv.org/abs/2512.07531 In observational studies, adjustment for energy intake changes the nature of the effect being estimated – from addition (increasing or decreasing intake of that food while...

SAVE THE DATE: The 2026 IEA European Congress of Epidemiology and 70th @socsocmed.bsky.social Annual Conference will take place in London, UK on 8th-11th September 2026! #EpiSky #EuroEpi2026

I'm excited to be charing the #SER2025 Causal Inference Late-breaking Abstract Speed Session at 17:30-18:00 in the Liberty room today!

So fantastic to reconnect with @nataliaortega.bsky.social in Boston of all places! #SER2025

"Globally, children’s Na intake was too high, while K intake was too low. Data were lacking in many countries. Interventions are needed to reduce Na and increase K from childhood, and monitoring should be improved" @drtomfrieden.bsky.social #PopHealthLab nutrition.bmj.com/content/earl...

Join us for the Causal Inference for the Health Sciences Symposium on March 20th at the University of Zurich! A day of insightful talks & networking with experts in causal inference & health research. Program and registration for in-person or online attendance: projects.unifr.ch/pophealthlab...

Announcement: Next week, Georgia Tomova will present "Understanding compositional data with fixed and variable totals using DAGs and data simulations". @georgiatomova.bsky.social 🗓️ Wednesday, November 27 🕔 16:00 - 17:30 Berlin time 📍 Hybrid (Charité Mitte or Zoom) Registration links 👇 #EpiSky

My talk on "depicting determinstic variables within DAGs" is now online. The talk explains how DAGs can be used to help with understanding & estimating causal effects involving derived variables (e.g. BMI) & compositional data (e.g. nutrition data). #EpiSky #CausalSky youtu.be/upj20Pw8jTU?...

Passed my viva with minor corrections today 🥳🥹 So difficult to comprehend that it’s happened! #EpiSky #CausalSky

Really excited to be hosting @nataliaortega.bsky.social in Leeds for the next two weeks! I anticipate lots of conversations about the challenges of doing causal inference in nutritional data! 😂 #EpiSky
