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 self-signaling electrochemical sensor based on molecular imprinting technology for the detection of Bisphenol A (BPA) in food samples. The sensor was constructed through sequential modification of the electrode with reduced graphene oxide (RGO) and CoNiFe Prussian blue analogue (CoNiFe-PBA), followed by electropolymerization of an MIP film using BPA as template and o-phenylenediamine as monomer. CoNiFe-PBA provides an intrinsic signal at ~ 0.47 V without external probes, originating from synergistic redox interactions among Co, Ni, and Fe. BPA rebinding reduces the signal via steric hindrance, enabling sensitive detection in food samples. Under optimal conditions, the sensor demonstrated a wide linear detection range (0.5-500 nM) and a low detection limit (0.19 nM). Owing to its high selectivity, sensitivity, and accuracy, the sensor offers a reliable approach for precise quantification of trace BPA in complex food matrices.
