Left ventricular remodeling with preserved function after coronary microembolization: the effect of methylprednisolone.
Article in European journal of medical research, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundThe objective of this study was to evaluate changes in left ventricular ejection fraction (LVEF) and left ventricular remodeling after coronary microembolization (CME) and to investigate the protective effects of methylprednisolone (MTP).
methodsCME was induced by injection of microspheres (42 μm Dynospheres) into left anterior descending artery of mini swine. The animals were divided into two groups. Group 1 (n = 9) received 120,000 microspheres and Group 2 (n = 7) received 120,000 microspheres following intravenous administration of 30 mg/kg MTP. Contrast-enhanced magnetic resonance imaging (CeMRI) was performed at baseline, 6 h after intervention, and 1 week later.
resultsIn Group 1, LVEF was significantly decreased at 6 h but recovered 1 week. This was accompanied by continuing left ventricular remodeling. In Group 2, LVEF remained unchanged at all assessment times. LVEF measured at 6 h and 1 week after CME in Group 1 and Group 2 was 0.39 ± 0.06 and 0.44 ± 0.04, and 0.44 ± 0.04 and 0.48 ± 0.03, respectively (Both P >0.05). Hyperenhancement at the anterior wall of the left ventricle was shown by MRI at 6 h in Group 1 but not in Group 2. The hyperenhanced area in Group 1 was 7.77 ± 1.49% of left ventricular mass.
conclusionsThe consequence of CME is left ventricular dilation with preserved LVEF. Pretreatment with MTP appears to have a cardioprotective effect on left ventricular remodeling.
