Learning to research less but better at @KU_Leuven. Statistics and models for medicine.

[Ben Van Calster @BenVanCalster]

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

This is a perfect example of why teaching the fundamentals of stats and probability will remain important

[Ben Van Calster @BenVanCalster]

We looked at dynamic random forest prediction models for central line-associated bloodstream infections on EHR from @UZLeuven.

We compared binary, multiclass, time-to-event, and competing risk outcome definitions. With @sibipx @laure_wynants

Systematic review with meta-analysis of >30 validations of 1 model: IOTA-ADNEX

[Lasai Barreñada @BarrenadaLasai]

Discover our latest research in @BMJMedicine! We conduct a systematic review and meta-analysis of external validations of the ADNEX model for ovarian cancer diagnosis, highlighting areas for methodological reporting improvement.

10 years ago, Prof. David Conesa dined with a group of motivated biostatistics students. Today, we celebrate the continuity of spirit! Once again, the @SEBiostatistics Student Conference was a success!! Proud that my students were part of it! 🤩 Thanks @the_prbb for hosting!!

What a great week at @ISUOG in Seoul!
Really happy and honoured that our work was recognised with the Young Investigator award and best in category for managing ovarian masses 🎉

[Lasai Barreñada @BarrenadaLasai]

@ISUOG Extremely honoured to receive such an amazing award from @ISUOG and the Scientific Committee. This could have not been possible without all the work of the collaborators.
See you in #ISUOG2024!

[Lasai Barreñada @BarrenadaLasai]

Wrapped up an amazing time at #ISCB44 in Milan! I had the opportunity to present a poster and meet so many great fellow statisticians. See you in #ISCB45!

[Laure Wynants @laurewynants.bsky.social @laure_wynants]

Now published. Shan Gao will be presenting this at #iscb44

[Lasai Barreñada @BarrenadaLasai]

@ysm_conference Thank you all for the wonderful conference! 😊

[Laure Wynants @laurewynants.bsky.social @laure_wynants]

PREPRINT

1 single clinical risk prediction model
47 external validations

Excellent pooled predictive performance. Despite heterogeneity in performance between settings/countries/centers, demonstrated clinical utility almost everywhere.

Interesting work @BarrenadaLasai

[Lasai Barreñada @BarrenadaLasai]

My first tweet for my first preprint! 🎉

Systematic review and meta-analysis of external validations of ADNEX model for ovarian cancer diagnosis.
Including critical appraisal with @TRIPODStatement and #PROBAST.
