Main finding · Future joint swellingResult — go to the resultOdds ratio 2.88 95% CI 2.61–3.18Authors' conclusion
This study identified a strong association between baseline joint swelling and subsequent swelling episodes in patients with PsA.
Study context
- Population
- Patients with PsA followed at the Tel Aviv Medical Center Rheumatology Institute; 44% male, mean age 48 y/o (SD 15), mean disease duration 1 yearjoints assessed in 492 patients
- Participants
- 33,456 patients
- Exposure
- Joints swollen at baseline vs joints not swollen at baseline
- Swollen at baselinen = 1,402
- Outcome
- Recurrence of joint inflammation (swelling, SJC68) in previously affected joints during follow-up
Methodological detailsreal-world data, single-centre, mixed-effects logistic regression adjusted for joint location and follow-up visit, Median 6 (IQR 4-9) follow-up visits
