Key result
Recurrent DVT had a higher unadjusted pulmonary embolism rate than a single event (22% vs. 9%), but this was not significant after age and sex adjustment (HR 1.23; 95% CI 0.43-3.57; P=0.68).
Why the study?

What are the risk factors and outcomes associated with recurrent deep vein thrombosis compared to a single event?
Hazard Ratio: 1.23 (95% CI 0.43–3.57)
Absolute Event Rate: 22% vs 9%
p-value: p=0.68
Recurrent DVT is common (22%) and associated with specific risk factors like obesity and abnormal coagulation, highlighting the need for targeted preventive measures.
No takes yet. Share an insight, caveat, or question.
No independent PE risk with recurrent DVT after adjustment; leaves open whether larger prospective studies or additional covariates would alter findings.
Asim et al. (2017) conducted a cohort in Deep vein thrombosis (n=662). Recurrent deep vein thrombosis vs. Single deep vein thrombosis event was evaluated on Pulmonary embolism (HR 1.23, 95% CI 0.43-3.57, p=0.68). Recurrent DVT had a higher unadjusted pulmonary embolism rate than a single event (22% vs. 9%), but this was not significant after age and sex adjustment (HR 1.23; 95% CI 0.43-3.57; P=0.68).
