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

Strain sensors in soft-material and flexible-electronic systems face a fundamental challenge: isotropic thermal expansion can generate parasitic signals that obscure true mechanical deformation. This issue is particularly severe in crack-based sensors, whose extreme morphological sensitivity causes thermally driven crack evolution to interfere with strain transduction. Inspired by the bead-chain morphology of Nostoc, we introduce a crack-based one-dimensional microspheres array (COMA) that stabilizes crack geometry under isotropic expansion, enabling a predictable, monotonic thermal response from which true strain can be accurately extracted. Conductive polyaniline (PANI)@ polystyrene (PS) microspheres unidirectionally assembled into grooved elastomers form discrete, crack-like junctions that convert ultralow mechanical deformation (≤0.5%) into pronounced electrical signals. The COMA sensor exhibits a stable thermal response of 75.2%°C
