Equilibrium radionuclide angiocardiography for the evaluation of right ventricular ejection fraction in patients with cardiac disorders.
Article in International journal of clinical and experimental medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo compare correlation between right ventricular ejection fraction (RVEF) derived from MRI and equilibrium radionuclide angiocardiography (ERNA) depicted from the left anterior oblique (LAO) view and anterior (ANT) view [designated as ERNA (LAO) and ERNA (ANT), respectively].
methodsTwenty-one patients with cardiac disorders received ERNA and cardiac MRI examination within 2 weeks were enrolled in this study. The region of interest (ROI) in right ventricle was depicted from the LAO and anterior (ANT) views to calculate the ERNA (LAO) and ERNA (ANT). Cardiac MRI was performed as served as reference standard to compare correlation between RVEF derived from MRI and ERNA (LAO)/ERNA (ANT), respectively. The repeatability was evaluated according to the intraclass correlation coefficient (ICC).
resultsRVEF obtained through MRI was closely correlated with that obtained through ERNA (LAO) view (r=0.883) and ERNA (ANT) view (r=0.891), respectively. Bland-Altam analysis indicated the RVEF derived from the ERNA (LAO) view was obviously underestimated in patients with right ventricular enlargement. Meanwhile, the RVEF derived from the anterior view was much closer to the RVEF derived from MRI compared with that obtained from the LAO view.
conclusionsERNA is effective for the determination of RVEF. LAO is still preferred for the determination of RVEF, but the RVEF may be underestimated in the patients with right ventricular enlargement. Determination of RVEF based on ANT is solely recommended in the determination of RVEF in patients with right ventricular enlargement and serves as a control.
