Some may be surprised at the number and variety of randomized trials of diagnostic tests/strategies looking at diagnostic impact (effect on patient-important outcomes) that investigators have conducted. doi.org/10.1016/j.jclinepi.2…

NEW preprint 'Stability of prediction models' @Richard_D_Riley arxiv.org/abs/2211.01061 Influenced by @f2harrell 'example models', different samples from a population to train models (small/mod. N) will lead to wildly different predictions for the same individual. #statstwitter

🌟NEW PREPRINT PAPER🌟 "Stability of clinical prediction models developed using statistical or machine learning methods" - with @GSCollins What is model (in)stability? How do we examine, present & quantify it? How does sample size impact (in)stability? arxiv.org/abs/2211.01061

Clinical prediction models estimate an individual's risk of a particular health outcome, conditional on their values of multiple predictors. A developed model is a consequence of the development...

Day 3! With a take home message about the "gold standard": There is no such thing as a gold standard. Every solution to solve lack of gold standard has its own disadvantages. Maybe we should move away from the notion that sensitivity and specificity are relative to THE truth.
