Predicting Depression and Anxiety Progression in Multiple Sclerosis from Longitudinal Clinical Data Using Machine Learning
This study demonstrates that while gradient boosting models using structured electronic health record data can predict depression and anxiety progression in multiple sclerosis patients, their limited predictive power (R² ≤ 0.28) is dominated by baseline scores reflecting regression to the mean, indicating that richer data sources beyond structured clinical variables are necessary for meaningful individual-level forecasting.
