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

backgroundCOVID-19 has caused a global shift in healthcare-seeking behaviour; however, presentation rates with serious conditions, such as stroke in low COVID-19-prevalence cities, has received less attention.

aimsTo determine if there was a significant reduction in stroke admissions, delivery of acute reperfusion therapies, or increased delays to presentation during the first wave of the COVID-19 pandemic.

methodsA multicentre, retrospective, observational cohort study was performed across three tertiary hospitals in Brisbane, Australia. Cases were identified using ICD-10 codes and then individually reviewed for eligibility using prespecified inclusion and exclusion criteria. All metrics were compared over 3 months from 1 March to 31 May 2020 with two corresponding 3-month periods in 2018 and 2019.

resultsThere was a mean of 2.15 (95% CI 1.87-2.48) stroke admissions per day in the examined pandemic months compared with 2.13 (95% CI 1.85-2.45) and 2.26 (95% CI 1.97-2.59) in March to May 2018 and 2019 respectively, with no significant difference found (P = 0.81). There was also no difference in rates of intravenous thrombolysis (P = 0.82), endovascular thrombectomy (P = 0.93) and time from last known well to presentation (P = 0.54). Conversely, daily emergency department presentations (including non-stroke presentations) significantly reduced (P < 0.0001).

conclusionsDuring the early months of the COVID-19 pandemic there was no significant reduction in stroke presentations, use of acute reperfusion therapies or delays to presentation, despite a reduction in ED presentations for any cause. Our results differ from the global experience, with possible explanations, including differences in public health messaging and healthcare infrastructure.
