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

objectiveThe aim of this study was to compare in-hospital mortality across waves in patients without and with a ceiling of care at hospital admission.

designA multicentre prospective cohort study.

settingFive tertiary hospitals in Catalonia, Spain, during four waves of the COVID-19 pandemic. Data from the first wave embraced from March to April 2020, second wave from October to November 2020, third wave from January to February 2021 and fourth wave from July to August 2021.

participantsAll consecutive adult subjects (older than 18 years old) admitted to any of the five aforementioned centres. All subjects had a confirmed SARS-CoV-2 infection (with a positive PCR test or antigen test) and an overnight hospital stay. Ceiling of care defined as the highest level of care that a patient will receive during medical treatment was assessed at hospital admission for all patients. PRIMARY MEASURE: In-hospital mortality.

resultsA total of 3982 hospitalised patients without ceiling of care and 1831 hospitalised patients with ceiling of care were included in the analysis. The adjusted ORs of in-hospital mortality in the second wave were 0.57 (95% CI 0.40 to 0.80), in the third 0.56 (95% CI 0.37 to 0.84) and in the fourth 0.34 (95% CI 0.21 to 0.56) compared with the first wave in subjects without ceiling of care. The adjusted OR was significantly lower in the fourth (0.38, 95% CI 0.25 to 0.58) wave compared with the first wave in subjects with ceiling of care.

conclusionsIn patients without ceiling of care, mortality decreased over time, suggesting better disease knowledge and management. In ceiling of care, only fourth wave patients were less likely to die than first wave patients. In a future infectious disease pandemic, it will be a challenge to improve the management of patients with ceiling of care.
