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

Polyamide (PA) has notable physical and chemical properties and is one of the most versatile synthetic materials in the industrial sector. However, its hydrophobicity creates significant challenges in its beneficiation and modification. Modifications of PA with chitosan nanoparticles (CNPs) can improve its undesired properties but are rarely found in the literature due to the weak interaction between the chemical groups of both structures. Surface hydrolysis mediated by enzymes can mildly improve the PA properties and create reactive sites. These sites can react with CNPs to confer enhanced properties to the fabrics, such as antimicrobial activity and flame retardancy. This study investigated the action of 14 hydrolases in the surface hydrolysis of 100% polyamide 6 (PA 6) fabric. Such an extensive study applying several enzymes for this process is uncommon. Under the optimum conditions, the hydrolyzed fabric was covalently bonded to the CNPs, generating material with reduced bacterial proliferation and flame retardancy properties. The uncommon covalent bond attachment achieved high material durability, even after five washing cycles.
