The relationship of the changes in lateral leads I and aVL in electrocardiogram with echocardiography and coronary angiography findings in patients with acute coronary syndrome.
Article in ARYA atherosclerosis, 2021. 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
backgroundElectrocardiographic (ECG) study is a principle for the symptoms contributed to the acute myocardial infarction (AMI)/acute coronary syndrome (ACS). The diagnosis of involved coronary artery based on ECG changes is still a challenge. This study is aimed to evaluate the association of mere changes in I and aVL leads with the involved region found through echocardiography and involved coronary artery through angiography.
methodsThis cross-sectional study was conducted on 100 patients referred with AMI/ACS symptoms that had mere ECG changes in I and aVL leads (ST elevation + Q wave/ST depression + inverted-T). Transthoracic echocardiography (TTE) and coronary angiography (CAG) were performed for the patients. The correlation of ECG with echocardiography and angiography was assessed.
resultsAmong the studied population, 39 patients (39%) were women with the mean ± standard deviation (SD) of age of 64.60 ± 9.39 years. There was no significant association between ECG changes in leads I and aVL with neither the stenosis of first diagonal (D1) coronary artery found through angiography (P = 0.580) nor the mid-anterior wall dyskinesia found through echocardiography (P = 0.380). A remarkable association between the echocardiographic findings representing mid-anterior wall ischemic dyskinesia with the stenosis of D1 coronary artery was detected (P < 0.001). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 100%, 54.54%, 94.68%, and 100% were respectively found as the diagnostic values of mentioned factors.
conclusionOur findings showed significant association between D1 involvement and mid-anterior dyskinesia in echocardiography, while the changes in ECG were associated neither with echocardiographic nor angiographic outcomes.
