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

Introduction: Since the beginning of the COVID-19 pandemic, in Brazil, there has been a high rate of deaths, mainly among those who were hospitalised due to the disease and those who needed intensive care units (ICUs) and mechanical ventilation support. Methods: The study evaluated the hospitalised patients with COVID-19 as well as subgroups considering those hospitalised patients who needed ICU treatment and those who received invasive mechanical ventilation in an ICU. The risk of death was compared in these three groups with adjustments for gender, age, race and comorbidities. A multivariable analysis was performed to identify the main predictors of death. A hospitalised patient was considered COVID-19 positive if they had a positive real-time polymerase chain reaction (RT-PCR) or serological test, followed by a notification form completed by a health professional, usually a medical doctor. The study was approved by the ethics committee of the institution (Certificate of Presentation of Ethical Appreciation n° 67241323.0.0000.5514; Study Approval Technical Opinion n° 5.908.611). Results: The study evaluated 2 031 309 hospitalised individuals with COVID-19. The case fatality rate was 33.2% (673 527/2 031 309). The case fatality rate was even higher among those patients who required ICU (372 031/665 621; 55.9%) treatment with the need for invasive ventilation support (240 704/303 505; 79.3%). In the multivariable analysis, the male sex (OR=1.14; 95% CI=1.13-1.15), older age [61 to 72 years old (OR=2.43; 95% CI=2.41-2.46), 83 to 85 years old (OR=4.10; 95% CI=4.06-4.14) and+85 years (OR=6.98; 95% CI=6.88-7.07)], race [mixed individuals ( Conclusion: Although the number of daily deaths from the coronavirus dropped during the COVID-19 pandemic in Brazil, our retrospective analysis showed a higher case fatality rate in patients requiring ICU, mainly when using invasive ventilation, compared with the rest of the world.
