Electrocardiographic findings and mortality in covid-19 patients hospitalized in different clinical settings.

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.
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
backgroundTwelve-lead electrocardiogram (ECG) represents the first-line approach for cardiovascular assessment in patients with Covid-19.
objectivesWe sought to describe and compare admission ECG findings in 3 different hospital settings: intensive-care unit (ICU) (invasive ventilatory support), respiratory care unit (RCU) (non-invasive ventilatory support) and Covid-19 dedicated internal-medicine unit (IMU) (oxygen supplement with or without high flow). We also aimed to assess the prognostic impact of admission ECG variables in Covid-19 patients.
methodsWe retrospectively analyzed the admission 12-lead ECGs of 1124 consecutive patients hospitalized for respiratory distress and Covid-19 in a single III-level hospital. Age, gender, main clinical data and in-hospital survival were recorded.
results548 patients were hospitalized in IMU, 361 in RCU, 215 in ICU. Arrhythmias in general were less frequently found in RCU (16% vs 26%, p<0.001). Deaths occurred more frequently in ICU patients (43% vs 20-21%, p<0.001). After pooling predictors of mortality (age, intensity of care setting, heart rate, ST-elevation, QTc prolongation, Q-waves, right bundle branch block, and atrial fibrillation), the risk of in-hospital death can be estimated by using a derived score. Three zones of mortality risk can be identified: <5%, score <5 points; 5-50%, score 5-10, and >50%, score >10 points. The accuracy of the score assessed at ROC curve analysis was 0.791.
conclusionsECG differences at admission can be found in Covid-19 patients according to different clinical settings and intensity of care. A simplified score derived from few clinical and ECG variables may be helpful in stratifying the risk of in-hospital mortality.
