Venous thromboembolism in COVID-19 compared to non-COVID-19 cohorts: A systematic review with meta-analysis.
Synthesis in Vascular pharmacology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 26 papers, 3 of them syntheses that pooled it.
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
backgroundMany studies confirmed an association between COVID-19 and venous thromboembolism (VTE). Whether the risk of VTE significantly differed between COVID-19 cohorts and non-COVID-19 cohorts with similar disease severity remains unknown.
objectivesThe aim of this systematic review with meta-analysis was to compare the rate of VTE between COVID-19 and non-COVID-19 cohorts with similar disease severity.
methodsA systematic literature search (MEDLINE, Embase and Google Scholar) was conducted from January 1, 2020 to March 31, 2021 to identify studies reporting VTE in COVID-19. Relative risks (RR) were estimated for the effect measure with 95% confidence intervals.
resultsSeven studies (41,768 patients) evaluated VTE in COVID-19 cohorts compared to non-COVID-19 cohorts. The overall risk of VTE (RR 1.18; 95%CI 0.79-1.77; p = 0.42; I
conclusionThere was no signal for a difference in VTE in COVID-19 cohorts compared to non-COVID-19 cohorts, except for the subgroup of patients hospitalized in the ICU. These results should be viewed as exploratory and further studies are needed to confirm these results.
