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

The bioaccumulation of hepatotoxic Microcystin-RR (MC-RR) in aquatic products poses a severe threat to human health via the food chain, underscoring the urgent need for sensitive detection methods. Herein, a self-powered electrochemical aptasensor was developed for on-site MC-RR monitoring based on ZIF-67/g-C3N4 heterojunctions. By coupling hydrovoltaic and photoelectric effects, the engineered built-in electric field significantly enhanced charge separation and water evaporation, amplifying the electrical signal by 11-fold under illumination. The aptamer-functionalized platform enabled specific MC-RR detection via modulating the interfacial charge transfer, achieving a wide linear range from 1 × 10− 14 M to 1 × 10− 10 M and an ultra-low detection limit of 2.36 × 10− 15 M. Furthermore, the sensor demonstrated excellent selectivity against interfering substances and was successfully applied to the analysis of aquaculture water and crucian carp samples. This work presents a sustainable, high-performance self-powered sensing platform for early cyanotoxin screening to safeguard aquatic food safety. Its advantages of simple operation and high sensitivity make it a promising tool for on-site food safety monitoring.
