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

Since changes in pharmacological treatments for severely ill patients with coronavirus disease 2019 have been incorporated into clinical practice, both by their use (corticosteroids and remdesivir) and by stopping them (e.g., hydroxychloroquine), we sought to compare the rate of intubation and mortality of intubated patients in our ICUs between the first and second waves of the pandemic.

designSingle-center, observational.

settingFour coronavirus disease 2019 designated ICUs at an urban Greek teaching hospital. PATIENTS: All adult patients with coronavirus disease 2019 consecutively admitted to ICU during the first (

resultsThe percentage of intubated ICU patients dropped from 82% during the first wave to 66% during the second wave (

conclusionsPharmacological adaptations and other measures may have led to fewer intubations over time. However, these changes do not seem to be translated into improved outcomes of intubated patients. Perhaps the same change in the use of drugs and protocols that could cause fewer intubations of ICU patients might be a reason of increased mortality in those patients who are eventually intubated. Furthermore, the relative staff inexperience and overall increase in patients' comorbidities during the second wave could have contributed to increased Acute Physiology and Chronic Health Evaluation II score and mortality of intubated patients.
