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

People with type 2 diabetes (T2D) are at a higher risk for myocardial infarction (MI) than age-matched healthy individuals. Here, we studied cell-based cardiac regeneration post MI in T2D rats modeling the co-morbid conditions in patients with MI. We recapitulated the T2D hallmarks and clinical aspects of diabetic cardiomyopathy using high-fat diet and streptozotocin in athymic rats, which were then subjected to MI and intramyocardial implantation of human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) with or without rat adipose-derived microvessels (MVs). hiPSC-CM alone engrafted poorly. Co-delivery of hiPSC-CMs with MVs yielded a smaller infarct area and a thicker left ventricle wall. Additionally, MVs robustly integrated into the infarcted hearts, improved the survival of hiPSC-CMs, and improved cardiac function. MV-conditioned media also promoted hiPSC-CM maturation in vitro, increasing cardiomyocyte (CM) size in an interleukin (IL)-6-dependent manner. Given the availability of MVs from human adipose tissue, MVs present great translational potential for the treatment of heart failure in people with T2D.
