Spondyloarthritis & psoriatic arthritis
Racial and ethnic determinants of psoriatic arthritis phenotypes and disease activity
Authors' conclusion
Despite similar swollen joint counts and medication use, non-white individuals have higher tender joint counts compared with White individuals. Phenotypically, they also were more likely to have radiographic axial involvement.

Main finding
As reported in the abstract
- Population: 77.4% non-Hispanic White, 2.2% Black, 7.1% Asian, 9.9% other races or multiracial; 11.8% Hispanic
- Hispanic and non-white individuals also had high rates of radiographic axial disease
- Hispanic and non-white vs Non-Hispanic White: P = 0.033
- Hispanic and non-white vs Non-Hispanic White: P = 0.308
- Hispanic and non-white vs Non-Hispanic White: P = 0.171
Observational data: associations, not effects.
