Authors' conclusion
Several PDs were linked to increased risks of developing AF.

- Outcome
- Incident AF
- Follow-up
- January 1, 2001 to December 31, 2023
Main finding
As reported in the abstract
Incident AF by overall PD
PD vs No PDAdjusted hazard ratio (95% CI)
whole cohort
1.28(1.27–1.29)
sibling analysis
1.32(1.29–1.35)
- Atrial fibrillation (AF) diagnosed during follow-up
- 213,048 (5.58%)
Observational data: associations, not effects.
Further findings
AF risk over follow-up time
- Associations strongest early in follow-up, progressively weakened over time, but persisted through the whole follow-up
