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

A zirconium-based MOF-on-MOF hybrid nanostructure (AIE-MOF@PCN-222, average size 3860 nm) was synthesized and characterized by SEM, TEM, XRD, XPS, FTIR, BET and TGA, which displays excellent peroxidase-like activity and stable aggregation-induced emission (AIE) properties. The dual-mode colorimetric-fluorescent sensing of formaldehyde relies on the synergistic mechanism of specific Schiff-base condensation, nanozyme catalysis and fluorescence resonance energy transfer (FRET). After parameter optimization, the sensor presents a linear response of 4-40 µM, with detection limits of 14.5 nM (colorimetric) and 1.78 nM (fluorescent). A 3D-printed portable device integrated with PDMS microfluidics was developed for on-site detection. In spiked shrimp and fish samples, the sensor achieves recoveries of 97.60-103.50% (colorimetric, RSD ≤ 2.95%) and 98.20-102.40% (fluorescent, RSD ≤ 3.12%), with relative errors below 1.51% relative to HPLC. This strategy provides a promising dual-mode platform with potential for portable HCHO screening in food matrices for HCHO detection in food matrices.
