Importance of ECG findings in COVID-19 patients: Predictor of in-hospital prognosis.
Article in ARYA atherosclerosis. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCardiac injury in COVID-19 patients confers a worse prognosis. The interpretation of electrocardiography can be beneficial in the early diagnosis of probable cardiac involvement. After adjusting for other variables, we sought to determine if the initial ECG on admission could add additional prognostic value.
methodsIn this single-center cross-sectional study, 1165 patients with a positive COVID-19 PCR between Feb 2020 and Nov 2021 were enrolled in our study. Patients were grouped according to their admitted units, and survivors to hospital discharge or non-survivors. Predictors of ICU admission and in-hospital mortality were determined using univariate analysis and a logistic regression model.
resultsThe mean age was 55.6 ± 16.2 years and 52% were male. Out of 1165 patients, 149 deaths (12.8%) were recorded during hospitalization. Sinus tachycardia was the most common dysrhythmia, followed by premature atrial and ventricular beats, sinus bradycardia, and atrial fibrillation (28.6%, 5.6%, 3.9%, and 2.1%, respectively). Age (p<0.001), sex (p=0.006), history of diabetes mellitus (p=0.002), hypertension (p=0.018), ischemic heart disease (p=0.004), and cancer (p<0.001) were more frequent among non-survivors. Among ECG findings, tachycardia, low voltage QRS, ST-T changes, and dysrhythmia were related to an increased mortality risk. However, in regression analysis, only sex (OR 1.89, 95% CI 1.2 to 2.9, p=0.004), age (OR 1.03, 95% CI 1.02 to 1.05, p<0.001), and initial tachycardia (OR 1.02, 95% CI 1.01 to 1.03, p<0.001) were independent predictors of in-hospital mortality.
conclusionOur data suggest that initial electrocardiographic findings could be helpful in distinguishing patients with an increased risk for ICU admission or in-hospital death.
