1 · What the graph read from 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.

2 · The registry

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

Cerebral venous thrombosis (CVT) causes significant disability and mortality. Current guidelines for CVT management support the initial use of unfractionated heparin or low molecular weight heparin followed by longer-term oral vitamin K antagonist (VKA). There has been increasing, albeit limited, evidence for the use of direct oral anticoagulants (DOAC) as an alternative to VKA. We performed a systematic review and meta-analysis of studies that compared the safety and efficacy of DOACs to VKA in treating CVT. A comprehensive literature search was carried out in Medline, Embase and Cochrane Stroke Group Trials Register using a suitable keyword/MeSH term search strategy. All studies published in English comparing outcomes of patients with CVT treated with DOAC or VKA were included. In total, 6 studies (5 observational studies and 1 randomized clinical trial) comprising 412 patients (age range 16-83 years) were analyzed. DOAC was used in 151 patients, while 261 received VKA. The follow-up period was 3-11 months. The efficacy of DOACs was comparable with VKA in terms of partial or full thrombus recanalization (RR 1.02, 95% CI 0.89-1.16) and excellent functional recovery with modified Rankin scale < 2 (RR 1.02, 95% CI 0.93-1.13). Patients treated with DOAC developed lower major bleeding events when compared to VKA, although this did not reach statistical significance (RR 0.44, 95% CI 0.12-1.59). We provide preliminary evidence to support DOAC as effective and safe alternatives to VKA in CVT treatment. We await the results of upcoming randomized trials to further support our results and validate the use of DOAC.
