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

objectivesAngiographic cortical early hyperemia (EH) is frequently observed after endovascular thrombectomy (EVT) for large vessel occlusion (LVO) stroke. The aim of the study is to investigate the relationship between EH and clinical outcomes.

methodsBetween January 2015 and September 2018, consecutive patients who underwent EVT for anterior circulation LVO stroke with optimal recanalization (modified thrombolysis in cerebral infarction 2b or 3) were included. Angiographic studies after immediate reperfusion were used for analysis for cortical EH sign. Clinical functional outcomes were evaluated with the modified Rankin Scale (mRS) at 90 days. Safety outcomes, including mortality and intracerebral hemorrhage, were assessed. The association of EH between clinical functional and safety outcomes was analyzed.

resultsA total of 143 patients were analyzed (mean age: 71 years; median National Institutes of Health Stroke Scale score: 18). A positive EH sign was observed in 88 (62%) patients. Good functional outcome at 90 days was significantly different between the EH

conclusionResults revealed that the presence of EH is associated with better clinical outcome at 90 days, but not associated with increased hemorrhagic complication. These findings with clinically relevant implications require further validation. KEY POINTS: • Angiographic cortical hyperemia is a common finding immediately after endovascular thrombectomy. • Presence of cortical hyperemia is an independent prognostic factor for good clinical outcome. • Hemorrhagic complication is not associated with cortical hyperemia.
