Missing data was handled inconsistently in UK prediction models: a review of method used

Clinical prediction models (CPMs) are statistical models or algorithms that use a set of predictor variables to calculate an individual's chance of developing or having a certain condition, and thus aid clinicians with the associated clinical reasoning and decision-making1. Three major phases can be identified in the CPM pipeline: (i) developing and internally validating a CPM; (ii) validating the model on new independent cohorts of patients (external validation), potentially adjusting or updating the model as needed; and (iii) implementing the model in clinical practice while monitoring its impacts2.
