Quantification of Contraction Synchronicity and Contraction Work in Coronary Artery Disease.
Article in Nuclear medicine and molecular imaging, 2017. 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
purposeThis study quantified the contraction synchronicity (CS; with 100% representing full synchrony and -100% dyssynchrony) and contraction work (CW, millijoules per centimeter squared; representing myocardial area) in patients with reduced left ventricular ejection fraction (LVEF) associated with coronary artery disease (CAD).
methodsCS, CW and LVEF in 104 subjects (54 CAD patients and 50 control subjects without CAD) were measured using rest electrocardiography-gated single-photon emission computed tomography (ECG SPECT). Contraction amplitude (CA), synchronous contraction index (SCI), and CW were evaluated using the program Quantification of Segmental Function by Solving the Poisson Equation (QSFP) developed in-house.
resultsThe mean CA, SCI and CW of 17 segments in the control subjects were 33.8 ± 4.1% (±SD), 96.6 ± 1.4%, and 6.9 ± 1.0 mJ/cm
conclusionAsynchrony shown using the QSFP is useful for CAD detection.
