A Case of Deep Vein Thrombosis After Recovery From COVID-19 and Its Association With Elevated D-dimers.
Article in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The coronavirus disease 2019 (COVID-19) continues to be a devastating disease for the elderly population, especially in long-term care facilities, and it presents with varying clinical presentations. We have ample evidence that COVID-19 can predispose to deep vein thrombosis (DVT) and pulmonary embolism (PE) during an active infection. Still, very few cases of DVT have been reported after recovery from COVID-19. The imbalance of the coagulation cascade and the increased release of certain coagulation factors play an essential role in promoting hypercoagulability and vascular endothelial dysfunction. It leads to a rise in the level of fibrin degradation products, D-dimers, which can remain elevated for up to several weeks, even after recovery. It has been suggested that the risk of DVT occurring after recovering from COVID-19 remains high for up to three months. We report a case of a 77-year-old long-term care female resident at a nursing facility, ambulatory at baseline, who was noted to be COVID-19 positive upon routine facility-wide testing per department of health guidelines. She was asymptomatic during her 10-day quarantine period. D-dimer levels during routine labs were high (initial D-dimer level of 1.87 mg/L FEU {normal value: 0.19-0.52 mg/L FEU}), but the patient had no clinical signs and symptoms of DVT. Ultrasound of the bilateral legs was not performed due to low clinical suspicion. The patient received an enoxaparin DVT prophylaxis dose during the quarantine period. Follow-up D-dimer levels were done at frequent intervals after recovery, but D-dimer levels continued to remain elevated up till six weeks after her 10-day quarantine period ended. Based on previous experience with other long-term care residents who suffered from COVID-19, bilateral lower extremity ultrasound was performed, which showed bilateral DVT. Elevated D-dimer levels are a predictor of hypercoagulation complications in COVID-19. Patients with persistently elevated D-dimer levels after recovery from COVID-19 should be screened for thromboembolic complications, even if they are asymptomatic. DVT can occur up to three months post-recovery from COVID-19 infection.
