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

objectiveAcute central retinal artery occlusion (CRAO) is an emergency with poor visual outcome. Intravenous thrombolysis within 4.5 h of vision loss is safe and may improve vision, but is rarely administered because of frequent delays in presentation. We describe a subgroup of CRAO patients presenting within 24 h of vision loss to a tertiary care center affiliated with a comprehensive stroke center. MATERIALS AND

methodsRetrospective review of 181 consecutive CRAO patients seen at our institution from 2010 to 2020.

resultsOut of 181 CRAO patients, 62 (34%) presented within 24 h of vision loss and tended to live closer to the hospital. These patients were more likely to be admitted to the hospital and receive comprehensive stroke work-up compared to patients who presented after 24 h of vision loss. Patients presenting after 24 h did not necessarily receive prior appropriate work-up at outside institutions. Conservative treatments for CRAO were administered to 20/181 patients, and only 3 patients received intravenous thrombolysis.

conclusionsPatients with CRAO do not present to the emergency department fast enough and diagnosis of CRAO is often delayed. Despite having a protocol in place, only 3/181 patients received IV thrombolysis, emphasizing the difficulty in administering very acute treatments for CRAO. Public education regarding CRAO is necessary to improve presentation times, management, and visual outcomes. Hospitals need to develop accelerated diagnostic pathway protocols for patients with acute vision loss so that CRAO patients may be diagnosed and be considered for potential acute treatments as quickly as possible.
