Nationwide trends in emergency department utilisation for acute retinal ischaemia in the USA, 2011-2018.
Article in The British journal of ophthalmology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
backgroundGuidelines recommend urgent evaluation for transient monocular vision loss (TMVL) and retinal artery occlusion (RAO), but emergency department (ED) utilisation for these conditions is unknown.
methodsWe performed a retrospective longitudinal cross-sectional analysis of the Nationwide Emergency Department Sample (2011-2018), a database of all ED visits from a representative 20% sample of US hospital-based EDs. We identified patients aged 40 and older with a primary diagnosis of TMVL or RAO and calculated the weighted number of total visits and admission rate by year. We used joinpoint regression to analyse time trends and logistic regression to measure differences according to demographic characteristics and comorbidities.
resultsThere were an estimated 2451 ED visits for TMVL and 2472 for RAO annually in the USA from 2011 to 2018. Approximately 36% of TMVL and 51% of RAO patients were admitted. The admission rate decreased by an average of 4.9% per year for TMVL (95% CI -7.5% to -2.3%) and 2.2% per year for RAO (95% CI -4.1% to -0.4%), but the total number of ED visits did not change significantly over time. Elixhauser Comorbidity Index and hyperlipidaemia were associated with increased odds of hospital admission for both TMVL and RAO. There were also differences in admission rate by insurance payer and hospital region.
conclusionOf the estimated 48 000 patients with TMVL or RAO annually in the USA, few are evaluated in the ED, and admission rates are less than for transient ischaemic attack or ischaemic stroke and are decreasing over time.
