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
Composite magnetoelectric (piezoelectric/magnetostrictive) materials are gaining an increased interest due to their appealing wireless actuation capabilities. For many applications, such as sensing, energy harvesting or cell electrostimulation, flexible and adaptable heterostructures are required. However, some of the proposed structures suffer from poor magnetoelectric performance due to their inherent stiffness and the resulting substrate clamping effects. Here, a highly flexible and conformable nanostructured ZnO(piezoelectric)/FeGa(magnetostrictive) magnetoelectric heterostructure embedded in a low Young's modulus elastomer (polydimethylsiloxane; PDMS) is presented. This heterostructure is designed to enhance wound healing via electric stimulation induced by low-intensity and low-frequency AC magnetic fields. In vitro testing using normal human dermal fibroblasts (NHDF) and human keratinocytes (HaCaT) cell cultures demonstrated high cell viability and no adverse effects under magnetoelectric stimulation. Moreover, the magnetoelectric stimulation significantly enhanced keratinocyte stratification and fibroblast collagen production, with remarkable improvements in cell migration compared to non-stimulated cells. These results underscore the potential of highly flexible magnetoelectric heterostructures as active dressings to improve wound healing processes, especially relevant for chronic wounds and other epithelial disorders.
