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 ternary nanocomposite, PEDOT:PSS/UiO-66-Cl@Ru, was successfully synthesized via a one-pot hydrothermal strategy for the ultrasensitive electrochemical detection of amaranth (AM) and Allura Red (AR). The conceptual advance of this work lies in the synergistic integration of halogen-induced intrinsic electroactivity, maximal atomic utilization of single-atom Ru, and the conductive bridging effect of PEDOT:PSS. This ternary design effectively overcomes the conductivity bottleneck of MOFs while delivering exceptional catalytic site density and enhanced interfacial stability. The resulting PEDOT:PSS/UiO-66-Cl@Ru platform delivered remarkable analytical performance, featuring wide linear ranges of 0.05–140 µM for AM and 0.07–50 µM for AR. The low limits of detection were 16.6 nM and 23.3 nM, with high sensitivities of 0.179 µA µM⁻¹ cm⁻² and 0.247 µA µM⁻¹ cm⁻² for AM and AR, respectively. Furthermore, the proposed sensor demonstrated excellent selectivity, reproducibility, and stability. Finally, the successful application of PEDOT:PSS/UiO-66-Cl@Ru in detecting AM and AR within beverage samples validates its practical utility for on-site food safety screening.
