1 · What the graph read from it

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.

2 · The registry

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

objectiveIn an effort to expand treatment for advanced heart failure, we sought to develop a tissue-engineered cardiac patch for constructive and functional in situ myocardial regeneration.

methodsAn extracellular matrix patch derived from porcine small intestine submucosa was incorporated with a controlled release of basic fibroblast growth factor. The patch was surgically implanted into the porcine right ventricle (group B, n = 5). Untreated extracellular matrix (group U) and Dacron (group D) patches served as control (n = 5/group). Cardiovascular magnetic resonance was performed in all 3 groups 60 days postsurgery to evaluate regional contractility with peak longitudinal strain, perfusion with relative maximum upslope, and extent of fibrosis/edema with extracellular volume fraction. Electrophysiologic-anatomic mapping was performed in group B. Histology and quantitative reverse transcription-polymerase chain reaction were performed for further tissue characterization.

resultsCardiovascular magnetic resonance-derived parameters were significantly better in group B compared with groups U and D (strain: group B = -16.6% ± 1.8%, group U = -14.7% ± 1.2%, group D = -9.0% ± 1.5%, P < .001; upslope: group B = 13.7% ± 1.1%, group U = 10.8% ± 1.3%, group D = 6.4% ± 1.8%, P < .001; extracellular volume: group B = 45% ± 7%, group U = 54% ± 10%, group D = 70% ± 10%, P = .003). Histology in group B showed a homogenous distribution of host cells, including tropomyosin and α-sarcomeric actinin-positive maturing cardiomyocytes. Group B demonstrated the greatest degree of vasculogenesis as determined by capillary density analysis (group B = 19.5 ± 6.2/mm(3), group U = 12.7 ± 2.5/mm(3), group D = 6.9 ± 3.7/mm(3), P < .001). Quantitative reverse transcription-polymerase chain reaction supported the histologic findings. Electrophysiologic-anatomic mapping in group B indicated positive electrical conductivity in the patch area.

conclusionsThe extracellular matrix patch enhanced with controlled release of fibroblast growth factor facilitated in situ constructive repopulation of the host cells, including cardiomyocyte and functional regeneration, increased regional contractility and tissue perfusion, and positive electrical activity in a porcine preparation.
