Transthoracic echocardiography compared with coronary angiography for patients with cardiogenic shock: A prospective cohort study.

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
Cardiogenic shock is the most severe form of acute heart failure. The aim of the current study was to investigate correlations between diagnostic parameters and the estimated ejection fraction in patients with cardiogenic shock. A total of 2,445 patients with acute myocardial infarction were subjected to coronary angiograms and standard 2D transthoracic echocardiography. Information for culprit vessel(s) and mitral regurgitation were collected. The Spearman's correlation test was used to assess the correlation between diagnostic parameters and estimated ejection fractions at a 95% confidence level. The angiographically-derived numbers of culprit vessels had a significant correlation with mitral regurgitation (r=0.907; P=0.034). The echocardiographically-derived mitral regurgitation was significantly correlated with the numbers of culprit vessels (r=0.896; P=0.04). Positive correlation was established between angiographically- and echocardiographically-measured left ventricular ejection fraction (r=0.356; P=0.045). The numbers of culprit vessels (P=0.058) and mitral regurgitation (r=0.99; P=0.001) were similar for angiography and echocardiography. Echocardiography- and angiography-derived results were correlated with the estimated ejection fractions of patients with cardiogenic shock. However, there is a substantial difference in the procedures of the two operational techniques.
