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

objectiveTo describe the characteristics, outcomes and predictors of a severe outcome of patients presenting with a SARS-CoV-2 infection to the ED of a major urban referral hospital in New South Wales, Australia, from January 2020 through February 2022.

methodsLinked healthcare and death registration records were used and included any person assigned a diagnosis potentially related to an acute respiratory infection in the ED and that had a linked positive COVID-19 detection. Logistic regression was used to determine predictors of a severe outcome (ICU admission or death) within 28 days.

resultsOf 2081 included COVID-19 patients, 238 (11.4%) had a severe outcome within 28 days of arrival at the ED. Among adults, the odds of a severe outcome increased with age, although the rate of increase in odds within age groups was statistically significant only in 30-64-year-olds (4% per year of age; confidence interval [CI] 2-6). Ambulance arrival (odds ratio [OR] 2.85; CI 1.76-4.78), higher triage urgency (category 1 or 2 compared with 4 or 5: OR 8.63; CI 4.41-18.12), and presentation during the pre-Delta (OR 6.18; CI 3.59-10.66) and Delta (OR 3.64; 95% CI 2.49-5.35) variant periods (compared with Omicron) were independently associated with increased risk of a severe outcome.

conclusionAge, ambulance arrival, higher triaged urgency, and presentation earlier in the pandemic were predictors of a severe COVID-19 outcome. Aged care measures and prioritising vaccination of older persons and aged care workers may have reduced severe outcomes in the elderly.
