Venous thromboembolism in an Asian COVID-19 cohort across 3 infection waves-a retrospective observational study.

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
Background: A high incidence of venous thromboembolism (VTE) in COVID-19 has led to international recommendations for thromboprophylaxis. With limited data on Asian patients with COVID-19, the role of thromboprophylaxis remains unclear. Objectives: To investigate the in-hospital incidence of VTE in an Asian COVID-19 cohort, describe the VTE trend through successive COVID-19 waves (wild-type, delta, and omicron), and characterize the risk factors for VTE. Methods: We performed a retrospective observational cohort study of hospitalized COVID-19 adults from January 2020 to February 2022. Objectively confirmed VTE were reviewed to obtain VTE incidence and trend. Subset analysis of critical (intensive care), moderate (oxygen supplementation), and mild cases hospitalized ≥5 days was performed to investigate risk factors and in-hospital hazards of VTE. Results: Sixteen VTE events occurred among 3574 patients. Overall, VTE incidence was 0.45%, or 0.21% in mild, 3.60% in moderate, and 5.38% in critical infection. The maximum cumulative risk of VTE was 1.14% at 14 days for mild, 8.13% at 21 days for moderate, and 11.55% at 35 days for critical infection. Thromboprophylaxis use in mild, moderate, and critical cases was 5.7%, 28.8%, and 81.7%, respectively. In multivariable analysis, the severity of infection remained the strongest independent predictor of VTE. Compared with mild infection, the relative risk was 8.26 (95% CI, 2.26-30.16) for critical infection and 6.29 (95% CI, 1.54-25.67) for moderate infection. Conclusion: Overall, VTE incidence in Asian patients with COVID-19 is <1% across successive waves. Patients with moderate and critical infections are at greater risk for VTE and should be considered for routine thromboprophylaxis.
