Relationship between ST-Segment Shifts in Lead aVR and Coronary Complexity in Patients with Acute Coronary Syndrome.
Article in Acta Cardiologica Sinica, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundST-segment shifts in lead aVR are associated with increased coronary atherosclerosis. However, there is insufficient data about the relationship between ST-segment shifts in lead aVR and coronary complexity. The aim of this study was to investigate this relationship.
methodsThis prospective, observational study included 236 patients with acute coronary syndrome who underwent coronary angiography. Electrocardiograms on presentation were reviewed in terms of ST-segment shifts in lead aVR. Inter-observer agreement was analyzed using kappa statistics for the presence of aVR lead ST segment shifts. The patients were divided into two groups according to their Sx scores (≤ 22 and > 22).
resultsThe mean age of the study population was 62.19 ± 12 years. Eighty-seven patients (37%) had complex coronary artery disease as defined by intermediate-high Sx scores, and 130 patients (55%) had ST-segment shifts in lead aVR. In multivariate logistic regression analysis, ST-segment elevation or depression ≥ 1 mm were independently associated with intermediate-high Sx scores.
conclusionsIn patients with acute coronary syndrome, the presence of ST-segment elevation or depression ≥ 1 mm in lead aVR may indicate coronary complexity.
