Evaluation of right ventricular dysfunction and prediction of clinical outcomes in acute pulmonary embolism by chest computed tomography: comparisons with echocardiography.
Article in The international journal of cardiovascular imaging, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 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
To evaluate the ability to identify right ventricular (RV) dysfunction, and to predict adverse outcomes of chest computed tomography (CT), we compared CT and echocardiography in acute pulmonary embolism patients. We analyzed 56 patients diagnosed by CT with acute pulmonary embolism, who underwent echocardiography within 48 h of CT scan from January 2004 to December 2008. From the CT scan, the ratio of RV diameter to left ventricular diameter (RVd/LVd), the presence of septal bowing and embolus location were determined. RVd/LVd (P < 0.001), septal bowing (P < 0.001) and proximal embolism (P = 0.016) were associated with echocardiographic RV hypokinesia. The odds ratio for adverse clinical outcomes was 19.2 for the combination of three CT parameters (RVd/LVd > 1, septal bowing, and proximal embolism), and 13.4 for RV hypokinesia (each P = 0.001). The positive predictive value (PPV) for adverse clinical outcomes for echocardiographic RV hypokinesia was 55.0%, and the negative predictive value (NPV) was 96.2%. The three-parameter combination predicted adverse clinical outcomes with a PPV of 54.5%, and a NPV of 94.1%. CT parameters including RV dysfunction were significantly associated with poor outcomes. Rapid risk stratification of patients with acute pulmonary embolism based on chest CT appears to be comparable with echocardiography, is clinically reliable, and may be useful in guiding management strategy.
