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

Magnetic separation offers a promising strategy for bacterial removal from aqueous systems due to its tunable specificity, biocompatibility, and facile recovery. However, the influence of nanoparticle size on removal efficiency and adsorption capacity remains unclear. Here, we systematically investigate size-dependent effects using porous magnetic particles covalently modified with polyethyleneimine (PEI). Porous magnets with diameters ranging from ∼50 to ∼420 nm were synthesized and functionalized with PEI to enhance electrostatic interactions with negatively charged bacteria. The resulting PEI-modified porous magnets induced extensive bacterial aggregation and exhibited high adsorption capacities for both Gram-negative
