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
In this study, the swelling properties and structural changes during the interaction with liquid media of biodegradable cross-linked polyurethanes promising from medical and environmental points of view are reported. To characterize the polyurethane samples, containing sucrose as cross-linking agent in different concentrations, in the dry state, and swollen in water and dimethyl sulfoxide (DMSO), low- and high-field liquid-phase NMR spectroscopic methods, such as relaxometry, diffusometry, and cryoporometry, were applied. Based on the NMR relaxation features of the swelling liquids and the swollen cross-linked polymers, the difference in the interaction with the two liquids was evaluated; furthermore, the rigid and mobile domains in the amorphous part of the polymer were successfully identified. The change of their ratio with the sucrose content and the restricted diffusion of DMSO in the swollen polymer network reflected the cross-link density and highlighted the role of dangling chains. The swelling process in DMSO was followed by the change of the
