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
To address the irreversible cross-linking of amidoamine (AA) hardeners, dynamic alternatives have been developed, but high viscosities and nontunable curing kinetics limit practical applications. We present a novel strategy to reduce the viscosity of dynamic AAs by several orders of magnitude and simultaneously tune their curing kinetics with epoxy compounds. Specifically, polysuccinamide- and polyglutarimide-based curing agents were synthesized from bulk chemicals and end-capped with secondary amine functionalities. The curing kinetics of the amidoamine-epoxy system were tuned via the chemical environment of the secondary amine, while the viscosity of the hardeners was controlled by varying the average amidoamine chain length. The versatility of these dynamic hardeners was investigated in conventional bulk adhesive formulations. Tensile and lap-shear experiments on these resins demonstrated strong adhesion (up to 11 MPa) and excellent rebonding capabilities. This straightforward synthetic strategy enables an attractive drop-in technology toward rebondable amidoamine-epoxy hardeners, starting from low-viscosity formulations with tunable curing kinetics.
