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

Objective: To evaluate the risk factors for the development of laryngotracheal injuries in patients with coronavirus disease 2019 (COVID-19) undergoing orotracheal intubation (OTI). Methods: A cohort study was performed with intubated patients diagnosed with COVID-19, hospitalized from March 1st to October 31st, 2020. They were called for outpatient follow-up after being discharged from the hospital. Results: There were 421 patients with COVID-19 (31%) who required OTI, of which the outcome was: hospital discharge for 172 (40.9%) and death for 249 (59.1%). Outpatient videoendoscopy was performed in 95 patients (55.2%). Conclusion: We observed a greater risk for the development of laryngotracheal injury in patients who presented an increase in leukocyte count at hospital admission with lymphopenia, hypoalbuminemia, increased arterial lactate, troponin, and total bilirubin, as well as endotracheal tube with larger caliber and pronation. Furthermore, patients who at the time of OTI showed greater inflammatory reactivity or developed coagulation disorders were also at greater risk.
