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
Self-healing optically transparent polyimides have potential applications in optoelectronic device fabrication. In this study, for the first time, we successfully prepared a novel self-healing polyimide film containing reversible disulfide bonds through chemical imidization by introducing cystamine as a self-healing functional monomer into the molecular structure of conventional polyimides. The incorporation of cystamine enabled the films to maintain high transmittance (>87%) and tensile strength (>99 MPa). Meanwhile, tensile tests showed that the prepared film with a cystamine content of 50% achieved an excellent self-healing efficiency of up to 91.8%. Stress relaxation tests further revealed that disulfide bonds were rapidly cleaved upon thermal stimulation and the network topology was rearranged to complete the self-healing process. These results suggest that the dynamic covalent polymer network made of aliphatic disulfide bonds presents a new strategy for the development of optically transparent polyimides with excellent self-healing properties.
