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

Ascorbic acid (AA) detection is a prior analyte for food safety and clinical diagnostics, yet traditional electrochemiluminescence (ECL) sensors depend on hydrogen peroxide (H₂O₂) coreactant whose instability degrades operational stability. To address this, we built a dissolved-O₂-driven ECL platform based on MoC nanoclusters/Co single-atom sites co-anchored on N-doped porous carbon (MoC NCs/Co SAs). The MoC NCs in the heterostructure activate dissolved O₂ to generate reactive oxygen species (ROS), while the Co SAs oxidize luminol, thus separating the two half-reactions in time. XRD, XPS, and TEM characterizations confirmed the hierarchical porous architecture and the EPR analysis verified singlet oxygen (¹O₂) as the active ROS. The sensor achieved a wide linear range of 568.79 pM to 28.39 mM (R² = 0.999) with a detection limit of 505.3 pM. Spike-recovery tests in fruit juices showed recoveries of 97.94-102.12%, confirming reliability in complex food matrix. By replacing external H₂O₂ with a dual-site catalytic cascade, this design eliminated H₂O₂ instability effect, and showed the good balance between the sensitivity and dynamic range, providing a practical platform for AA monitoring in food quality control.
