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

backgroundDeep cerebral venous thrombosis (CVT) is an uncommon condition with a high morbidity and mortality. The optimal treatment approach for deep CVT remains uncertain and due to its low prevalence, randomized trials are not feasible. We showcase a straight sinus thrombosis treated with a large bore aspiration and performed a meta-analysis of the available literature to characterize and evaluate the various treatment modalities for patients with deep CVT.

methodsWe conducted a systematic search in PubMed, EMBASE and Ovid Medline using appropriate keywords/MESH terms search strategy. All patients with thrombosis involving the deep venous sinuses were included if treatment records were available. Outcome measures included recanalization of the affected sinus, good functional outcome assessed by a modified Rankin scale (mRS) of 0-2 or reported independent functional outcomes, permanent neurological deficits, further hemorrhage and mortality.

resultsA total of 69 studies comprising 120 patients were included in the analysis. Anticoagulation was the most common treatment (85.8%), whilst local intrasinus thrombolysis was performed in 40.0% of the patients and mechanical endovascular modalities were employed in 20.0% of the patients. Recanalization of the occluded sinus was seen in 83.5% of the patients while 62.6% patients achieved good functional outcome. There was considerable morbidity with 60.7% having a permanent neurological deficit, 23.3% having further hemorrhage after admission and 18.6% mortality. In the cohort receiving anticoagulation, 65.3% achieved good outcome but intracranial hemorrhage at presentation was associated with poorer outcome, permanent deficits, further bleeding and mortality.

conclusionAnticoagulation is an effective treatment strategy for deep CVT; however, patients with intracranial hemorrhage at presentation often have poorer outcomes and early endovascular strategies could be considered in this subgroup.
