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

In urethral damage/stricture prevention, open and harsh urethral microenvironments and isotropic compression and swelling properties of exogenous implants render urethral repair intractable. Here a dynamically urethra-adapted and obligations-oriented trilayer hydrogel was engineered to integrate scarless urethral repair. Therein, the diethylacrylamide-hydroxyethylacrylamide (HEAm) (D-H) hydrogel layer featuring high anti-fouling performance prevent adhesions of bacterial and blood cells, and its poor swelling avoids urethra occlusion. The upper swellable and verteporfin (VP)-loaded N,N'-methylenebisacrylamide-poly (N-isopropylacrylamide) (BP) layer encourages urethra regeneration through expediting cell migration and proliferation. The rigid and water-resistant Zein middle layer opposes urine voiding-arised BP shedding, urethral diastole/contraction, inward BP swelling-arised urethra occlusion and urine permeation. Importantly, systematic proteomic and genomic analysis reveals that such hydrogel scaffolds expedite epithelial & vascular regenerations, attenuate tight cell junction, oppose inflammation microenvironment and regulate extracellular matrix secretion and metabolism to realize integrated urethral repair. The microenvironment-adaptable design concepts provide reliable rationales to engineer urethral regeneration scaffolds.
