Work Strain Intensifies Inflammation in ACPA-Positive Rheumatoid Arthritis
New cohort data suggest physical job demands may worsen early joint inflammation in antibody-positive disease but effects ease with treatment.

This association weakened after disease-modifying treatment began, highlighting an early window where mechanical stress may matter most.
