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
Contractile engineered cardiac patches hold great potential for treating myocardial infarction, serving as biological ventricular assist devices (BioVADs). However, optimal design and attachment of cardiac patches remain insufficiently explored, although both are essential for the mechanical support of damaged hearts. This study presents a platform for personalized macroscale patches with a multi-zonal microarchitecture combining a regenerative zone for cell alignment, a stiff force transmission zone for load transfer, and an elastic attachment zone enabling integration. Based on computational modeling, the design is implemented using a custom G-code generator for melt electrowriting (MEW). Digital image correlation reveals up to a 2.6-fold strain difference between scaffold zones under physiological deformation, confirming zonal interplay. Biaxial testing with preconditioning shows scaffold mechanics replicating native myocardium properties up to 10% strain. For epicardial suture attachment, a reinforced outline enables shape-morphing and increases suture retention 2.16-fold. Dynamic BioVAD cultivation with fibrin-embedded cardiomyocytes significantly (p = 0.01) improves cell alignment versus controls. Finally, in a porcine myocardial infarction model, the BioVAD achieves complete epicardial attachment and vascular ingrowth within 7 days, compared to partial attachment in controls. This study highlights MEW as a versatile platform for tailoring cardiac scaffold mechanics to support tissue integration and cardiac function.
