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.
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
Excess free radicals can have some negative effects on human health. In this paper, a nanozyme was successfully constructed by the coordination of copper ions and tannic acid, and its structure and elemental distribution were determined by Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray photoelectron spectroscopy. Free radical scavenging experiments confirmed that it possessed superoxide dismutase-like activity, catalase-like activity, and hydroxyl radical scavenging ability. The results of thermogravimetric analysis experiments demonstrated that it possessed good thermal stability. A polyacrylonitrile hybrid nanofibrous membrane loaded with Cu/TA nanozyme was successfully constructed by electrospinning technology, and the maximum scavenging rate of DPPH and ABTS radicals can reach 64.22% and 58.44%, respectively. The nanofiber membrane also exhibited the ability to protect cells from oxidative stress damage. Therefore, the hybrid nanofibrous membrane has a broad application prospect in fields such as food preservation and biomedicine.
