Machine learning–based prediction of 12-month change in 6MWD in pulmonary arterial hypertension: a retrospective prediction model development study
The six-minute walk distance (6MWD) is a key prognostic marker in pulmonary arterial hypertension (PAH), but predicting individual changes remains challenging. This study aimed to evaluate whether machine learning (ML) models can predict the relative 12-month change in 6MWD using baseline data. In this retrospective, s...
