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

Background: Cerebral venous thrombosis (CVT) is a rare thrombotic condition which is traditionally treated with anti-coagulation therapy. Subsets of patients with severe CVT have been treated with endovascular thrombectomy (EVT). Despite the high estimated mortality associated with severe CVT, there has been only one randomized control trial done regarding safety and efficacy of EVT in severe CVT compared to standard medical management. Evidence in this area is lacking. Objective: The aim of this systematic review is to analyze all existing literature and generate robust information regarding the role of EVT in the management of patients with severe CVT. Methods: This systematic review and meta-analysis followed PRISMA guideline. PubMed, Embase, Google Scholar, and CNKI were searched for eligible studies from 2007 to 2021. Safety and efficacy of EVT were evaluated by meta-analyzing recanalization status, the good functional outcome at follow-up, recurrent CVT, new hematoma. A pooled proportion with a 95% confidence interval was derived from a meta-analysis of various outcomes (CI). Results: A total of 33 studies comprising 610 patients treated with EVT were included for analysis which comprised one randomized control trial, one prospective study and 31 retrospective studies. Based on pooled data, 85% of patients had good functional outcome, 62% had complete recanalization, 5% had all-cause mortality, and 3% had catheter related complications. The efficacy outcomes in this analysis had a significant heterogeneity and a subgroup analysis was also done to explain these findings. The minimum time of follow up was 3 months and varied EVT techniques were used across the studies. Conclusion: This meta-analysis suggests EVT may be safe and efficacious in treating patients with severe CVT. Registration: Our protocol was registered with PROSPERO: International prospective register of systematic reviews with the registration number CRD42021254760.
