New Model Enhances Pulmonary Fibrosis Prediction in RA

11/28/2025

Summary

Story summary

A study in Arthritis Care & Research finds a combined genetic and clinical model better predicts pulmonary fibrosis (PF) in early rheumatoid arthritis (RA) than genetics alone.
Researchers analyzed data from 1,115 RA patients in Sweden and identified age and rheumatoid factor positivity as predictors.
The combined model reached an AUC of 0.75, vs. 0.62 for the genetic risk score.
Limitations include selective high-resolution CT examinations and potential methodological changes.
