This study evaluates clinical predictors of pain persistence after total joint replacement in OA patients, finding that pre-surgical pain levels are not related to post-surgical pain and multi-factorial models do not reliably predict outcomes.

The paper identifies four chronic pain traits using clustering and network analyses, revealing stable neurotraits that categorize patients into distinct neuropsychotypes.

This study shows that placebo pill response in chronic pain patients depends on brain structure, functional connectivity, and psychological factors, with machine learning predicting response magnitude.
