ImpactHigh impact
The discussions highlight the significance of proper sample size determination, emphasizing its role in improving model validity and reproducibility.
Abstract in brief
External validation is crucial for assessing the performance of clinical prediction models on new, independent data to ensure their reliability in real-world settings.
The article proposes methods to determine the minimum sample size needed for external validation of models predicting continuous outcomes, using four specific criteria related to variance explained, calibration, and outcome variability.
These methods help researchers plan studies more effectively by estimating the required sample size to achieve precise performance measures or assessing if existing datasets are sufficient, as demonstrated through a case study on predicting fat-free mass in children.]

Minimum sample size for external validation of a clinical prediction model with a continuous outcome https://t.co/xt0UzWVsa8
An unexpected (for me) consequence of recent work on sample size for prognostic models is that it that in some cases the minimum sample size for external validation is greater than that for model development.
