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

Surface-attached, degradable polymer hydrogels with potential antimicrobial activity are reported. They were obtained by ring-opening metathesis copolymerization (ROMP) of a monomer with potential bioactivity and a monomer that carries a benzophenone cross-linker and a hydrolyzable group. The hydrolyzable group was either an ester or an anhydride group. The copolymers thus obtained were spin-coated onto silicon wafers and UV-irradiated to induce C,H cross-linking of the benzophenone groups and obtain the target polymer networks. Immersion of these networks into aqueous media triggered network degradation. The degradation speed depended on the nature of the intended break points (ester or anhydride groups), the number of cross-links per polymer chain, and the surrounding medium. By releasing bioactive polymer fragments to the medium ("leaching") and by regenerating the hydrogel surface during the degradation process, the hydrogels potentially have two ways to prevent biofilm formation on their surface.
