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

Effective microbial control in water-associated environments, such as hospital sinks, is critical for preventing the spread of antimicrobial resistance in healthcare settings. Antimicrobial coatings represent a promising means for microbial control; however, their application on water-associated surfaces is challenging. Therefore, durable antimicrobial coatings that retain efficacy under challenging conditions, such as frequent water flow, are needed. To address this challenge, this study focused on water-resistant coatings formed by a silicone oil Pickering emulsion composed of hydrophobized 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidised cellulose nanofibres (CNF). We evaluated the performance of antimicrobial agent incorporation into the coatings under conditions simulating hospital sink surfaces. Most formulations achieved 99% (≥ 2-log
