‼️‼️ You may remember our newest submission category, ✨Preliminary Reports✨ How do our wider academic peers feel about this? Well, you can read about 8 external experts' opinions in this #FullAccess article here! 👇 #d1e290" target="_blank" rel="nofollow noopener">tandfonline.com/doi/full/10.10…

This is a great qualitative research paper. It sheds light on questionable research practices. But more importantly it demonstrates direct replications in qualitative research work as you would expect: independent teams reach basically the same conclusions royalsocietypublishing.org/rsos/article/1…

The constant stream of poor biomarker research in biomedical research journals makes me think my article "How to Do Bad Biomarker Research" must have been hugely influential :-) fharrell.com/post/badb #Statistics #biomarker

"Once a paper is published ... it is more harmful to one's career to point out the fraud than to be the one committing it."

In our latest podcast episode, @ChrisHughen sat down with @francoimpell to discuss risk factors in sports medicine. We dive into causal versus non-causal mechanisms, challenges in defining risk factors, the importance of transparency in research, the illusion of control in clinic practice, and much more. youtu.be/_-0yndWOf-w

Science and Medicine in Football is committed to promoting robust and reliable research. Our newest submission category for small-sample intervention studies (✨ Preliminary Reports✨) is another step in the process. Rationale and instructions below👇 #d1e302" target="_blank" rel="nofollow noopener">tandfonline.com/doi/full/10.10…

New 'Preliminary Report' submission format at Science and Medicine in Football. An idea that should be interesting for other journals! Explicitly make space for honestly reported smaller sample-size studies #d1e305" target="_blank" rel="nofollow noopener">tandfonline.com/doi/full/10.10…

@lakens, @JennyMurphy2, @JoeWarne1, Cristian Mesquida, Anne Hecksteden, Brice Batomen, Chinchin Wang, Tim Meyer. I also greatly appreciate reviewers from outside sport science and medicine, who offered their time, expertise, and feedback to support this (pilot) initiative.

Happy to announce @SciMed_Football’s new 𝗣𝗿𝗲𝗹𝗶𝗺𝗶𝗻𝗮𝗿𝘆 𝗥𝗲𝗽𝗼𝗿𝘁 category for small-sample studies, a pragmatic step to address the spread and misreporting of underpowered football research. Grateful to all co-authors for months shaping the submission requirements.

This piece of artwork was inspired by the following study by @carly_perry24, @AidenChauntry, and @fchamp1 Read it here 👇 tandfonline.com/doi/full/10.10…

Tess Baker amazes once more with her brilliant fusion of art and science! Thank you, Tess! PS: For those wondering how many more artworks Tess will share… your guess is as good as mine! No idea! She’s an artist and makes them only when inspiration hits :-(

Very common to ask patients to rate pain from "no pain" (0) to "worst pain imaginable / possible" (10). Here is a randomized trial showing anchor for pain score of 10 should be "extreme pain" (TL;DR: we want to evaluate pain, not imagination) jpro.springeropen.com/articles/10.11…

✨When science meets art. 💫 Tess Baker, a statistician from McGill University, has a special gift: transforming studies into artworks. Thank you, Tess, for sharing this with us!

In our latest work, we demonstrate that risk estimates for patients are HUGELY uncertain due to model uncertainty, data uncertainty, and population uncertainty. Even when based on large sample sizes. @laure_wynants @ESteyerberg arxiv.org/abs/2506.17141

This study is of better methodological quality than previous ones and includes data on 5,200 runners (it is the largest study so far and a casual inference approach was used). It showed that the higher the ACWR, the lower the injury risk. Oops! bjsm.bmj.com/content/early/…

I'm pleased to announce the publication of two important papers in Sports Medicine on the first every large replication project in sport and exercise science. Read the full papers: link.springer.com/article/10.100… link.springer.com/article/10.100…

@GMignemi_ @lakens Interesting perspective. Could you provide an example of a definition that allows one to make claims? Or elaborate a bit more.

@lakens Well, I do not totally agree. It depends on what we define with "exploratory" and how we are drawing inference. It's not all about p-values and testing.

Researchers should not make claims based on exploratory analyses because the probability that these claims are wrong can be unacceptably high. doi.org/10.1080/026404…

📢 See you in Charlotte! On June 4th and 5th, I'll be speaking at the VII FSI Conference on High Performance in Soccer at the Bank of America Stadium, organised by @fsitraining_ and @charlottefc. For more information, visit fsi.training/en/fsi-hub-eve… #Soccer #Conference
