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
Single- and two-photon stereolithography are high-resolution three-dimensional (3D) printing techniques that are widely used to fabricate complex microstructures. However, the resulting structures have high cross-linking and density, which limits their recyclability. Existing approaches to addressing this issue typically rely on chain-growth polymerization, which requires photoinitiators and additional reagents for recycling. In this study, we present an anthracene-based photocurable resin that undergoes reversible photodimerization, enabling phase transitions between the solid and liquid states without photoinitiators or additives. Using this resin, we fabricated and recycled 3D microstructures via two-photon lithography, demonstrating over ten successful reprocessing cycles with minimal degradation. In addition, the resin is also compatible with single-photon microstereolithography, highlighting its versatility. These findings suggest a promising route for sustainable high-resolution additive manufacturing.
