Α 6-month, multicenter, observational study investigating the treatment of venous thromboembolism in Greece (VICTORIA 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
backgroundReal-world data are needed to inform clinical practice with regards to anticoagulation treatment for persons with venous thromboembolism (VTE).
objectivesTo identify the type and duration of antithrombotic treatment in persons with VTE. Anticoagulation dosage and persistence/adherence were among the secondary objectives.
methodsA multicenter, observational, prospective study conducted in Greek adults with VTE with two on-site visits -baseline and at three months- and a telephone follow-up at 6 months.
resultsA total of 600 eligible persons were enrolled. The index event was 'PE only' in 50%, 'DVT only' in 40%, and 'DVT+PE' in 10%. Risk factors were categorized as temporary major (21%), temporary minor (37%), and persistent (43%), with active cancer present in 18% of patients. All VTE patients received anticoagulants: 73% received oral anticoagulants (72% DOACs, 1% VKAs) and 70% received parenteral anticoagulants. Treatment was oral only in 30%, parenteral only in 27%, and both in 43%. The most common DOAC was apixaban (47%). Extended anticoagulation (>6 months) was administered to 41% with only 9% (18/198) of those on DOACs receiving a reduced dose. Persistent risk factors predicted extended anticoagulation, while diabetes, COVID-19, and temporary minor risk factors did not. Adherence/persistence rates were similar between DOAC and non-DOAC-treated patients.
conclusionVTE was mainly treated with a combination of parenteral and oral anticoagulants. DOACs, primarily apixaban, were the most common oral treatments. Forty percent of patients received extended anticoagulation, mostly at standard dosages. Adherence and persistence rates were high for both DOAC and non-DOAC treatments.
