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

Millions of people suffer from corneal infections and inflammatory conditions, and a contact lens that not only corrects vision but also continuously protects against microbes and inflammation could transform ocular therapeutics. Compared with plasmonic metal nanoparticles, such as silver or gold, iron oxide nanoparticles are well known for their biocompatibility, low toxicity, and low cost. To our knowledge, this work is the first to demonstrate the integration of iron oxide nanoparticles into commercial contact lenses. Nanoparticles were characterized using X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy and transmission electron microscopy. Optical properties were assessed using UV-Vis spectroscopy and COMSOL simulations. Catalytic activity was evaluated by methylene blue degradation in the presence of H
