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

Mature biofilms are difficult to eradicate because the extracellular polymeric substance (EPS) matrix shields embedded bacteria from chemical and mechanical attack. Here, we report a porcupine-spine-inspired photo-responsive dynamic offensive bio-interface that dismantles mature biofilms through electrically actuated mechanical penetration and light-driven oxidative stress. A high-aspect-ratio nano-dagger array undergoes reversible nanoscale deformation (∼110 nm) under an alternating electric field, while a photo-responsive heterostructure generates a surface photovoltage (∼364 mV) that enhances reactive oxygen species production. Mechanical penetration continuously disrupts the biofilm-surface interface, exposing bacteria within the EPS matrix to oxidative attack. This synergistic mechanism enables nearly complete biofilm eradication under complete immersion in bacterial suspensions of 10
