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

Metal-organic frameworks (MOFs) are often acted as potential candidates for the construction of efficient nanozymes due to their unique metal-ligand assembly structure, which can mimic different enzyme activities by modulating the metal nodes and ligand environment. In this study, a three-in-one composite metal-organic framework nanozymes (CeCu-MOFs) with excellent intrinsic peroxidase-like, oxidase-like, and catalase-like catalytic properties have been successfully prepared in environmentally friendly manner by a one-step chemical deposition method. Meanwhile, a catalytic platform for signal amplification was designed for quantitative measurement of ascorbic acid (AA) using the oxidase-like characteristic of CeCu-MOFs. The constructed colorimetric sensor achieved selective identification and accurate measurement of AA, demonstrated good linearity in the range 0.1-50 μM with a detection limit of 0.063 μM. We, further developed a portable smartphone-based platform for visual colorimetric determination of AA in real samples in point-of-care (POC) fashion by utilizing a portable paper-based device.
