The use of axial diameters and CT obstruction scores for determining echocardiographic right ventricular dysfunction in patients with acute pulmonary embolism.
Article in Japanese journal of radiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
purposeTo evaluate the accuracy of cardiac computed tomography (CT) parameters and pulmonary artery (PA) obstruction (OS) scores in determining the echocardiographic right ventricular dysfunction (RVD) in hemodynamically stable patients with acute pulmonary embolism (PE). MATERIALS AND
methodsA total of 120 patients with acute PE were included in the study. Right ventricle/left ventricle ratio (RV/LV); PA axial diameter; superior vena cava (SVC) axial diameter; and Ghanima, Miller, Qanadli, and Mastora obstruction scores were obtained using CT. RVD was assessed by echocardiography. The patients were divided into two groups based on the presence or absence of RVD.
resultsRV/LV ratio, SVC axial diameter, PA axial diameter, and Miller, Qanadli, and Mastora scores were significantly increased in the RVD group. Multivariate logistic regression analysis showed that RV/LV ratio [OR 6.36 (2.02-279.46 95 % CI), p = 0.01] and PA axial diameter [OR 5.02 (1.02-1.26 95 % CI), p = 0.03] were independent predictors of echocardiographic RVD. Predictive values of these parameters were improved when combined with other intragroup cutoff values. A cutoff value for the RV/LV ratio of >1.08 had 81.43 % sensitivity, 52.08 % specificity, 71.3 PPV, and 65.8 NPV for prediction of RVD.
conclusionTomographic axial diameters enable more accurate predictions of RVD than OS scores do.
