Impact of SARS-CoV-2 infection therapies on the risk of venous thromboembolism and cardiovascular events from the SEMI-COVID-19 Registry.

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
This study aimed to assess the impact of SARS-CoV-2 therapies on the risk of venous thromboembolism (VTE) and other cardiovascular events. A retrospective, multicenter, observational study included hospitalized patients in Spain due to acute SARS-CoV-2 infection from March 2020 to March 2022. A total of 184,324 hospitalized COVID-19 patients were included, with a mean age of 67.5 (± 16) years of whom 58.4% were male. Among the comorbidities, arterial hypertension was the most common, affecting 52.5% (9618 patients), followed by dyslipidemia in 39.5% (7237 patients), diabetes mellitus in 23.7% (1748 patients), and atrial fibrillation in 10.6% (1948 patients). The overall mortality rate was 17.4% (3183 patients) and 9.9% (1819 patients) required admission to an intensive care unit. Cardiovascular events occurred in 4.08% (748 patients), with VTE occurring in 2.78% (510 patients), myocardial infarction in 0.75% (137 patients), and ischemic stroke in 0.55% (101 patients). Among therapies, beta-lactams were used in 66.7% (12,228 patients), systemic corticosteroids in 56.9% (10,424 patients), and tocilizumab in 11.6% (2128 patients). Multivariate analysis revealed an independent association between VTE and the use of tocilizumab (adjusted OR 2.07; p < 0.01), corticosteroids (adjusted OR 1.44; p = 0.02), and macrolides (adjusted OR 0.58; p < 0.01). None of the therapies were associated with the risk of myocardial infarction or ischemic stroke. In this large national cohort, tocilizumab and corticosteroids exhibited an independent association for the risk of VTE, but not for myocardial infarction or ischemic stroke.
