There are going to be an awful lot of analyses that need redone when people finally accept that collider bias is a major issue in unweighted analyses of UKBB data

I attended two CAUSALab Summer Schools, and spent nearly 2 years working through the design and implementation. In the end, I am proud of having done exactly the work I said I would do in my application. I believe it is the first target trial emulation of adherence to Canada’s Food Guide.

This project is especially meaningful to me. Back in 2021, I proposed it in my postdoc funding application. At the time, I actually had no idea how to actually implement a target trial emulation 😅. I knew that this was the right framework to improve nutritional epidemiology studies. #nutepi

Canada’s Food Guide recommendations support healthy aging, but optimal muscle strength and function likely require more than just following CFG: more protein foods, and physical activity.

Thanks for the suggestion. I have not yet used pubpeer. Looking forward to trying it

I guess I had the intuition it would not be published, since I had only sent a detailed abstract and outline for the letter. So, there was no preprint, but I am thinking about writing it anyway. Unsure where it’d land because the prompt for the letter is really the article in the specific journal
